{sung like the Foreigner song "Feels Like the First Time"}
The S3 Spyder Arctic G2 445nm directly-injected diode laser (hereinafter, probably just referred to as the "Arctic") is an extremely powerful self-contained, handheld laser.
It is rated to produce almost 1 watt of laser radiation at 445nm (spectrographically measured at 439.48nm {low} and 441.40nm {high}) in the royal blue part of the spectrum.
This amazing laser was in the Guiness Book of World Records as “The most powerful handheld laser in the world”!!! 
It comes in a very sturdy aluminum body that has been hard-anodized, and feeds from a single 18650 Li:ION rechargeable cell (which is included along with the charger).
It also comes with LaserShades laser safety glasses -- which must be used every time you fire up this studly little laser...you don't want to end up like this guy: --->
This may look funny, but I assure you folks, this is no joke!!!
***EXTREME CAUTION!!!***
The USS Lantree is a quarantined vessel by order of Starfleet Command.
Do not board.
...o wait, wrong warning!!! 
***EXTREME DANGER!!!***
This laser can produce up to 1 watt of laser radiation at 445nm (royal blue), and can cause instant and permanent eye damage from an accidental reflection or accidental direct exposure!!! You need to know what you're doing and have the appropriate safety precautions for a CDRH Class IV laser device in place before you energize this laser!!!
Destruction of the eye isn't the only ocular (eye) hazard here:
Exposure to high levels of blue & violet radiation can also wreak havok!!!
Big Scary “Laser” (the word 'laser' is spoken with “air quotes” like Dr. Evil does in the Austin Powers movies)
SIZE
To use your shiny new (or corroded old) Arctic, feed it the included 18650 Li:ION cell first (see directly below), and ***THEN*** you can go set fire to the dead wingless legless fly that you found in your box of raisins*...er...uh...set fire to the side of the Bemis Industries building in south Seattle WA. USA.*
To use the laser module (it has multiple operational modes thanks to its SmartSwitch™) {which is why it is the G2, not the G1}, follow these instructions:
1: Press the rubberised tailcap button until it clicks, and then release it.
The first LED on the barrel (a group of three arranged in a line on the opposite side as the SmartSwitch™ button) will begin flashing.
2: Click the SmartSwitch™. After the first click, the first LED will be steady-on and the second one will be flashing.
3: Click the SmartSwitch™ again. The first and second LEDs will be steady-on and the third one will be flashing.
4: Click the SmartSwitch™ a third time. Both the first and second LEDs will be flashing.
5: Hold down the SmartSwitch™ briefly and the second & third LEDs will be flashing.
6: Hold down the SmartSwitch™ briefly again. All three LEDs will flash three times, then go into battery status monitoring mode.
If you are not used to using a CDRH Class IV laser (and very, very few people really are!), you'll want to start out with the training lens in place.
The SmartSwitch™ prevents accidental and unauthorized activation of the laser by requiring a short sequence of clicks and click-holds to unlock the laser.
Once the laser is unlocked, the default operating mode for the laser is low power, pulse wave, constant on operation. This means the laser operates at 5% of the maximum power output, making it 20 times safer. When used in conjunction with the training lenses, output power is further reduced 5 times, making the laser only 1% as hazardous to the human eye or skin than at maximum power.
Once you are ready to experience maximum 100% power, it takes only 2 clicks to change the mode and mere seconds to replace the lens. The SmartSwitch™ is the world's most innovative and safest laser system ever created.
The following modes are available:
- Low Power (10% of maximum) , Constant Wave, Constant On
- Low Power (10% of maximum) , Pulse Wave (6Hz / 50%) , Constant On
- Max Power , Constant Wave, Constant On
- Max Power , Pulse Wave (6Hz / 50%) , Constant On
- Secure Locked Mode
The laser starts off in low power, blinking.
To change to steady-on mode, click the SmartSwitch™ once.
To cycle between full power and low power, give the SmartSwitch™ a short hold.
To lock the laser, give the SmartSwitch™ a longer hold (~3 seconds).
At any time, three short clicks followed by two short holds unlocks the laser.
Before firing up this studly little laser, you *MUST* be certain that you have the furnished laser safety glasses on!!!
The ones on the left (Argon Laser Safety Goggles) are not the ones you'll receive, but they do have an OD (Optical Density) of 5.00 at wavelengths of 515nm and shorter -- so they'll work quite well if I happen to accidentally sit on or step on and subsequently cause the furnished LaserShades to become busted.
The Arctic has a safety interlock dongle built into the tailcap -- this allows it to comply with FDA/CDRH requirements for a Class IV laser product.
This dongle (or "safety pin" as some have called it) can be removed by pulling it straight out. Doing so will completely disable the laser -- that is, the Arctic cannot be made to function even if a fully charged battery is left in place.
Restoring operation is as simple as pushing the dongle back into the opening in the tailcap for it; pushing in on it until it no longer moves.
The laser module comes with a hinge-lidded presentation case (that has a magnetically-closing lid) with a foam cutout for the module and most of the lenses (not including the one affixed to your Arctic at the moment). You may store the Arctic in this case if desired.
*This is Worm Quartet...one guy (Reverend Shoebox) and three worms.
The song "Find The Dead Wingless Legless Fly In Your Box Of Raisins" is from the album "Faster than a Speeding Mullet".
To charge the battery in your Wicked Lasers S3 Spyder Arctic, unscrew and remove the tailcap, throw it into the the dustbin (garbage can), tie off the bin liner (plastic garbage bag), carry it to the outdoor wheelie bin (wheeled garbage can), throw it in, slam the lid down, roll the wheelie bin to the curb, and wait patiently for garbage day so that the dustman (garbage man) empties the wheelie bin into his dust lorry (garbage truck)...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.
Tip the used 18650 cell out of the barrel and into your hand, and pop it into the included charger.
Insert a freshly-charged 18650 cell into the barrel, flat-end (-) negative first. This is the opposite of how batteries are installed in most flashlights, so please pay attention to polarity here.
Screw the tailcap back on, and be done with it.
Aren't you glad you didn't throw that tailcap into the dustbin now?
Current usage measures 384mA (minimum CW output) to 1,140mA (1.140A) (maximum CW output) on a known-fully charged 18650 cell.
To charge the 18650 cell, place it in the charging cradle, orienting it so its button-end (+) positive is on the same end of the chamber in the charger that has a (+) embossed on its upper surface (in this case, the end of the charger that the power cord goes in).
Plug the charger into any standard (in the United States) two- or three-slot 110 volts to 130 volts AC 60Hz receptacle.
A red light on the charging cradle should now come on; this indicates charging is in progress. When the 18650 cell has reached full charge, the light on the charging cradle will turn from red to green.
At this point, unplug the charger, remove the charged cell from the charging cradle, and install it in the laser as directed above.
This is a laser module, not a flashlight. So I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a front porch in effort to try and expose the bare Metalmarineangemon - er - the bare Metaltrailmon - um that's not it either...the bare Metalsusanoomon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! - now I'm just making {vulgar term for feces} up!!!), let my mother's big dog's ghost or my sister's kitty cats spring a leak (uranate) on it, hose it down with a gun, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoñata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. Therefore, this section of the laser's web page will seem a bit more bare than this section of the web page on a page about a flashlight.
This is a directly-injected laser though, who's active components are the laser diode and the collimating lens. So it should withstand accidents better than a DPSS (diode pumped solid state) laser - the type of laser assembly found in yellow (593.5nm), green (532nm) and blue (473nm) laser pointers & laser modules (handheld or laboratory). These lasers have several additional components (crystals, filters, etc.) in the optical train, and you can knock them out of alignment by doing little more than looking at them the wrong way. And if any of these components are knocked out of whack, you'll no longer get your yellow, green, or blue laser beam.
You still do not want to intentionally drop your S3 Spyder Arctic though, because it's a rather expen$ive precision optical instrument.
***EXTREMELY IMPORTANT!!!***
This laser is a CDRH Class IV instrument, and the photons generated by it are much higher in energy than the photons generated by a red laser of equivalent power (not that you'd want to shoot your eye out with a 1W red laser anyway!!!); so you definitely do not want to shine it into your eyes, other people's eyes, pets' eyes, for that matter, the eyes of any person or animal you encounter. 
Eye damage can occur faster than the blink reflex can protect them, regardless of what species' eyes you irradiate with this laser. So just don't do it.
And for Christ sakes (and for heaven sakes and for Pete sakes and your sakes too) do not shine the S3 Spyder Arctic (or any other laser for that matter!) at any vehicle, whether ground-based like a motorcycle, car, or truck, or air-based like a helicopter, airplane, or jet. And if you shoot it at a person in the dark and he turns out to be a police officer, he may think he's being targeted, unholster (pull out) his gun, and hose you down with it.
I know I just said this, but it bears repeating: You shine it in your eyes, not even when the S3 Spyder Arctic's battery has pooped out and it is below lasing threshold
This is a CDRH Class IV laser device. Treat it with respect, and it'll treat you with respect.
This laser is water-resistant but not submersible, so please be careful around sinks, tubs, toilets, fishtanks, pet water bowls, or other places where water or water-like liquids might be found. However, you need not worry about using it outdoors when it's raining or snowing.
The case is made from 6061-T6 Aircraft-Grade Aluminum, and is treated with a black HA-III (hard anodized) finish.
The beam has a divergence of less than 1.5mRad (milliradians), and has a diameter of 1.50mm when it exits the product.
According to the web page on the S3 Spyder Arctic, it produces a TEM00 (transverse electromagnetic mode 00) beam - that is, it produces a beam with a Gaussian power distribution; circular with a central hotspot and dimmer corona. This is a typical laser mode, and is how many lasers (well, most lasers for consumer use anyway) are designed to operate.
The beam from the Arctic is not perfecly circular; it is oval (somewhat egg-shaped) like beams from all directly-injected diode lasers that do not have special beam shape corrective optics.
The high-power lens ("window" actually) is AR (antireflective) coated on both sides; this helps greatly with minimising loss of intensity due to reflective losses in the window.
Operating temperature range is between 32°F (0°C) and 100°F (38°C).
Using the Arctic beyond this temperature range is a rather severe no-no!!! 
From somebody who knows their {vulgar term for caca; rhymes with "pit"} about lasers, comes the following information about this laser:
A spot on a perfectly white wall, assuming the wall does not char:
At 7 inches, should your pupil fully dilate, the spot hits the border
between effectively Class II and effectively Class IIIa. Maximum safe
time to stare at it from that distance, should your eye focus the spot
that close, is 1 second. Probably less due to the blue factor.
At 29 feet, the spot is at the border between effectively Class I and
effectively Class II. At this distance, the spot is safe to stare at for
2,500 seconds, even with a fully dilated pupil. At greater distances than
that, it is safe to stare at indefinitely. This is according to 21 CFR
1040.10.
===============================================================
Aim that laser into a white high power LED, and maybe about half a watt
of yellow light will come out. That is about 200 lumens. The LED will
not be safe to stare into. With such an LED of the usual lambertian
radiation pattern, I figure around 60 candela or 60,000 MCD. You may get
somewhat more.
This laser will fluoresce most magenta, pink, red, orange, yellow, and
green fluorescent objects. Some green-glowing yellow objects could
produce 300-400 lumens of light, with an intensity of 80-125 candela
(80,000-125,000 MCD).
For comparison, if you look broadside at the filament of a clear 75 watt
120V light bulb rated to produce 1190 or so lumens and to last 750 hours,
that is about 120 candela. The ratio of candlepower to lumens is less
with the light bulb because it distributes light more widely and evenly
than a "lambertian" source does (such as a fluorescing or
beam-illuminated spot on a diffusing surface like a piece of paper).
With a light bulb having a visually straight linear filament, ratio of
lumens to candela is close to and ideally the square of pi, which is 9.87.
With a lambertian radiator such as a beam-illuminated or fluorescing
spot on a diffusing flat surface, the ratio of lumens to candela is
ideally pi (3.14).

The laser power meter I have is simply not capable of measuring the tremendous power output of this laser (est. ~1.0 watt!!!) at maximum candiosity*...er...uh...I mean...maximum POWER.
I remeasured on 10-09-10 (or "09 Oct 2010" if you prefer:
Measures 37.8666mW on "low" with the training lens in place.
Measures 151.2734mW on "low" WITHOUT the training lens on.
All measurements were made on a Sper Scientific Pocket Laser Power Meter # 840011.
Measures 48.555mW on "low" with the training lens.
Measures 46.755mW on "low" with the training lens *AND* the high-power lens in place,
so the high power lens does cut back the output power, but only slightly.
I got a LaserBee laser power meter that can measure up to 2.50W on the afternoon of 06-13-11 (or "13 Jun 2011" or even "Jun 13, Twenty Double Sticks" if you prefer), and can now measure this laser at its maximum output.
Measures 719mW (high) and 84mW (low) on this meter.

EXTREMELY, CRITICALLY IMPORTANT!!!
Even though these are inhabited structures, in the above five photographs, I was absolutely, positively, 100% certain that the beam terminus was well away from windows, doors, or other apertures where somebody might become accidentally irradiated!!!
***VERY IMPORTANT!!!***
I made absolutely, positively, 100% certain that no aircraft of any type were in the vicinity when the following three photographs were taken!!!

Photograph taken at ~5:09am PST on 11-22-10 (or "22 Nov. 2010" if you prefer) in Federal Way WA. USA.
This is what the Arctic did to the furnished pair of LaserShades.
I have two other pairs of laser safety goggles that are highly effective at the Arctic's wavelength; so I was easily able to sacrifice these LaserShades in the name of science without robbing myself of eye protection.

A third photograph of the beam indoors; taken at 7:19pm PDT on 10-07-10 (or "07 Oct 2010" if you prefer).
This is a tobacco-free home, so I'm not certain just what the particulate matter (or contaminants) in the atmosphere are that would make the beam show up in this manner (show up this well).
Those red "splotches" on the ceiling are from a Laserpod that was operating in the vicinity at the time these photoghraphs were taken.
***VERY IMPORTANT!!!***
These three photographs were taken indoors in a location that
would absolutely forbid the accidental irradiation of people or pets!!!
The following two photographs show that something rather queer is happening to the beam:
Distance: ~12 inches.
Distance: ~7 feet.
I cannot explain just how the major axis of the beam is rotating 90° when the distance is the only variable here.
For both photographs, the Arctic was placed on a stable surface and was not bumped or even touched between exposures; the camera was on a tripod and it was not turned either.The following four photographs show that something rather queer is happening to the beam:
Distance: ~12 inches.
Distance: ~7 feet.
Distance: ~12 inches.
Distance: ~7 feet.
The 50% ND (neutral density) filter from my ProMetric 8 Beam Cross-Sectional Analyser was used for the lower pair of photographs -- this is also the cause of the secondary "ghost" beam spot seen in the last photograph.

I shot a video of this laser destroying a Crooke's Radiometer; please see the video linked to directly below:
ALL OF THE OTHER VIDEOS NOW HAVE THEIR OWN WEB PAGE BECAUSE THERE ARE JUST TOO MANY OF THEM AT THIS TIME!!!
This is the radiometer showing laser damage to the black portion of its vanes -- all four vanes are damaged in this fashion.
There doesn't appear to be sufficient damage to the vanes themselves to destroy the radiometer...best guess here is that when the black material incandesced (burned), it outgassed, queering the near-vacuum and/or the gas fill of the "bulb". If the pressure inside the "bulb" increased, that would indeed cause the radiometer to malfunction in the manner described on its web page.
TEST NOTES:
Test unit was sent by Steve of Wicked Lasers on 07-15-10 (or "15 Jul 2010" if you prefer), and was received at 12:51pm PDT on 09-27-10 (or "27 Sep 2010").
The long lead time was rather expected; Wicked Lasers got a huge influx of orders and they simply were not able to build Arctic lasers fast enough!!!
***EXTREMELY, SUPER DOOPER CRITICALLY IMPORTANT!!!***
This is a Class IV laser product!!!
Eye exposure will cause INSTANT (and permanent!) damage, and it is a hazard (with regard to burn injury and fire) to skin, clothing, and any other flammable materials as well!!!
You don't want baby brown recluse spiders, mosquito wrigglers (larvae) or Western Tiger Swallowtail butterfly caterpillars (larvae)...I mean you don't want AN UNWANTED FIRE!!! 
To put it as briefly as possible, you must use this laser with ***EXTREME CAUTION***, and use the protective eyewear furnished with the laser ***EVERY TIME*** you fire it up!!!
The very high output power isn't the only eye injury hazard here...you also need to be aware (or made aware) of potential photochemical damage to the eyes and skin from exposure to very intense radiation at wavelengths ranging from 500nm (blue-green) to 400nm (violet) -- and shorter wavelengths of course:

Setting fire to ***ANY*** structure, whether it be with a cigerette lighter & gasoline, a barbecue lighter & hairspray, or even with a powerful laser like the Arctic is as illegal as H-E-Double-Bendy-Straws!!! You will be arrested and hauled off to jail, and be labelled a firefly...er...uh...FIREBUG for the remainder of your natural life.
UPDATE: 10-01-10
¡HUSOOS CRISTO!
I have some anecdotal evidence that some variants of the 18650 cell supplied with the Arctic may fail rather catastrophically while in the charger.
*** VERY IMPORTANT!!!***
THIS (AS FAR AS I KNOW ANYWAY) APPLIES ONLY TO THE 18650 CELL IN THE GREEN OUTER COVERING, NOT THE ORANGE ONE!!!
From a posting on the Laser Pointer Forums (and used with explicit written consent; not just implied oral consent) comes the following {no changes to spelling, syntax or grammar were made}:
Hello everyone as you may know I've had my Arctics for a little while now.
I originally charged-up one of WL green 1300mAh 18650 batteries and while it didn't last long, all was fine.
Last night I needed to recharge that same WL 18650 battery. I used the same charger that I charged with last time around, and I've been using that same charger (one of several I have) for about 2 years now.
About an hour into charging I heard an explosion & large flash and awful burning smell from the room the charger & batteries where. Both my Fire Alarm & Burglar Alarm went off at the same time.
The WL 18650 battery had EXPLODED all over the place, and burn the wall, table top it was sitting on, scorched 3 other chargers that were sitting near it not plugged in and not being used at the time. It also scorched the side of the TV it was near. Pieces of the exploded battery flew across the room and light fire to my bedding linens.
Needless to say I had my hands full taking care of all this, in the end I'm left with ruined bed linens. Scorched table top, wall, side of 40" HDTV, 3 other scorched chargers from being near it and a ruined charger and an AW IMR battery sitting near it; not to mention all the pieces of the WL battery and fire/soot smell.
Spent must of the night and early this morning cleaning-up the best I could and got a Commercial Ionizer this morning to cleanup the air in the house to rid the house of that nasty fire smell.
I am very lucky that one it didn't burn my house down, and two I wasn't hurt because just 10 minutes before the Explosion I went in that room to checked on those batteries; thankfully it didn't explode in my face at that moment.
Someone once asked if the WL 18650 is a protected battery, I can tell you now for certain NO it's not.
I have heard of similar incidents more than just once, which kind of rules out a horribly unfortunate fluke.
I have seen Tenergy 18650 cells being mentioned rather frequently as a direct replacement for the 18650 cell included with the Arctic; if you have the 18650 cell with the green covering, it may very well behoove you to consider getting one or more Tenergy cells.
Since this is an issue with the battery and not the laser itself, I will not be decreasing the 5-star rating I furnished the Arctic.
***EXTREMELY, CRITICALLY IMPORTANT!!!***

this data is INFORMATIONAL ONLY and should be used solely for this purpose!!!
UPDATE: 10-11-10
This is the glass lens and metal lens cover for high-power lens; note how the glass lens ("window" actually, because it does not focus or modify the light in any way) fell off.
Here, let's show you with a photograph...*snap*...*click*...and it's off to the Fotomat we go:
The other lenses in the set have a metal collar inside (that holds the glass element in place) that is unscrewed with the use of a spanner wrench; no such collar was found in this unit.
Was this by design or is this simply a fluke?
UPDATE: 10-16-10
My sister vacuumed my room yesterday morning, completely unaware that the high-power lens was still on the floor. As a result, I no longer have it because it very likely went up the vacuum cleaner.
Although the chances of finding it are remote, the probability of this occurring is not mathematically zero -- especially if the vacuum cleaner she used is P-whipped.
UPDATE: 10-17-10
I have heard back from my contacts (yes, "contactS" in the plural) regarding the now-MIA lens, and a new one is being sent out.
So that new (but still fairly dreadful) "
" icon won't be here forever.
UPDATE: 10-19-10
I tested the Arctic for the presence of quasi-CW operation, and found none -- that is, it operates in true CW mode, both at minimum and maximum intensities.
Here, let's let this photograph of an oscilloscope screen do the talking here:
See the completely flat line?
If this laser operated in quasi-CW mode, you'd see a "jagged" line instead.
UPDATE: 10-19-10
No, you aren't seeing things.
Yes, a same-day update.
There have been scattered reports of the laser diode failing in the Arctic with the "training lens" in place; some users came to the conclusion that this lens may be reflecting too much laser radiation back into the diode itself, causing subsequent failure.
So I measured the reflected radiation at just 8.240mW (with the Arctic at full power and directing its beam at the inner surface of this lens as it would be during actual use) -- clearly, this is quite insufficient optical power "feedback" to cause diode failure. So you need not be concerned WHATSOEVER at using the training lens for its intended purpose as it poses no threat at all ("not no way, not no how" as they say) to the Arctic's laser diode.
UPDATE: 10-20-10
No, you aren't seeing things.
Yes, a same-day update.
Some vignetting of the Arctic's beam appears to be occuring along the major axis (the wider of the two axes; shown here oriented horizontally), as the following photograph demonstrates:
See how the edges at the extreme left and right are rounded?
That's because the edges of the beam along that axis are being vignetted ("cut off") by the edges of the aperture (the hole that the laser beam escapes from). It is not known just how much power is being lost in this fashion, but I would not expect it to be any more than a few tens of milliwatts at full power -- certainly nothing to be concerned about with a laser of this power.
UPDATE: 11-05-10
Note how the paint is coming off the Power button.
Since this is mainly a cosmetic issue that in no way affects functionality; no points will come off the Arctic's rating because of this.

UPDATE: 11-26-10
From somebody who knows their {vulgar term for caca; rhymes with "pit"} about lasers and optics (Don Klipstein), comes this -- regarding the apparent twisting of the beam that I photographically demonstrated yesterday:
Dear Craig Johnson,
I saw your stuff on the Arctic having major axis in one direction at 12 inches and 90 degrees from that at 7 feet.
Look for someplace in between where the beam is round.
The reason for this is usually astigmatism - where the beam has divergence from one axis corresponding to one "waist location", and divergence from the other corresponding to a different "waist location". Laser diodes often do this, while in general other lasers do not.
The "waist" is where the beam is narrowest. The beam converges approaching the "waist", and diverges after passing through the "waist".
Sometimes the waist does not exist in reality, but only as a mathematical projection of its existence rearward of where the beam starts. In that case, the beam diverges every inch of the way from where it actually starts.
A cylindrical lens can be used to move either the "parallel to E-field waist" or the "perpendicular to e-field" waist. If the two coincide into a single waist, then the beam has the same shape at all points far from the waist. (In the waist, the 90 degree difference happens again if the beam is oblong - lower divergence and wider waist width go hand-in-hand.)
UPDATE: 11-28-10
From somebody who knows their {slang term for poo-poo; rhymes with "wrap"} about lasers (Don Klipstein), comes this, regarding the spectra of the laser diode in the Arctic that I loaned him:
Dear Craig Johnson,
I have some findings here, mostly spectral!
1: Central wavelength of this one looks to me close to 441 nm. I will be doing a redermination.
2: I have achieved fine detail spectra. These are attached.
3: The spectral lines are "repeated-for-each-wavelength" reflections of the beam. At that point, the path length is about 35 feet. Each of these (as well as undiffracted beam which is far to the left) is highly oblong, 90 degrees from the way the beam is highly oblong when it exits the laser. The initially narrower dimension diverges more, as predicted. The initially-wider dimension may have a waist at some distance from the device for that matter - I have yet to get that far. The initially-narrower dimension appears to me to have its waist fairly close to where the beam exits the device.
Here are the three spectra he furnished:
Minimum power.
Maximum power.
Referenced to a neon glow lamp; third order spectrum at minimum power.
He writes:
This time, I had the laser shining onto a neon lamp. I had the camera looking at the laser-illuminated glow lamp through a diffraction grating.
In the previous ones, I had the laser reflect from a diffraction grating onto a wall.
UPDATE: 11-29-10
From Don Klipstein again, comes this spectrum of the Arctic on "high" mode; the neon lamp was again used as a reference:
UPDATE: 12-02-10
From Don Klipstein again, comes this beam terminus photo montage:
This shows the beam spot at five different distances, from 2 inches to 20 feet.
UPDATE: 12-04-10
The replacement "standard" (high-power) "lens" (actually, a window) has arrived, so that somewhat dreadful "" icon can now be removed.
This lens is AR (antireflective) coated on both sides.
UPDATE: 12-13-10
Performed spectroscopy of fluorescence of a tritium Glow Ring when irradiated with this laser.
UPDATE: 12-16-10
Being a CDRH Class 4 device, in the United States the Arctic must have (in addition to the existing safety features) but does not have:
1: Mechanical beam shutter
2: LED (or other light source) emissions indicator (The Arctic does have LEDs, but they do not actually indicate whether or not laser radiation is being generated)
Therefore, at least ½ a star has to come off its rating.
UPDATE: 12-21-10
Performed spectroscopy of fluorescence of two more objects when irradiated with this laser.
UPDATE: 01-06-11
Removed the "unboxing" video because I was receiving an excessive amount of negative commentary about it -- like how I was such a careless ass and even worse.
UPDATE: 04-22-11
I found the following brief piece about the Arctic in the "Manufacturer's Showcase" section in this month's issue of Laser Focus World magazine:
UPDATE: 06-14-11
I got a LaserBee 2.5W USB Laser Power Meter yesterday, and wasted no time in measuring this laser with it.
Measures 719mW (high) and 84mW (low) on this meter.
UPDATE: 11-11-11
Here are the charts produced by the LaserBee:
Low: 85mW.
High: 715mW.
PROS:
EXTREMELY POWERFUL output for such a small, self-contained unit
Powerful enough to burn, destroy, and leave wrinkles everywh...o wait!!! wrong infomercial!!!
Color (royal blue @ ~440nm) is exceptionally vibrant and unusual for a handheld laser
Battery it uses is rechargeable; never have to find disposables for it
CONS:
Timing for using the SmartSwitch™ is somewhat critical; if your timing sucks, you can't get this laser to fire off
(This is a crucial safety feature, and can rather easily be overlooked!)
High-power "lens" was very easily broken -- that's what nocked that last 0.05 star off its rating...however, if I find that it was manufactured incorrectly, I'll consider it a fluke and restore that last 0.05 star.
