(In reference to the large padded envelope I received from DinoDirect.com at 3:07pm PDT on 06-28-11):
{sung like the Foreigner song "Feels Like the First Time"}

The 1000mW 447nm Waterproof Adjust Focus Blue Laser Pen (hereinafter, probably just called a "blue portable laser" or even just a "blue laser") is a royal blue-emitting, directly-injected diode laser. That is, it produces deep blue laser radiation directly, without the need for messy, fragile nonlinear crystals like those green laser pointers and the amberish-yellow and slightly greenish-blue ones as well. It uses a 18650 rechargeable Li:ION (lithium ion) cell -- you just charge it back up when it poops out...never have to run to the store for batteries.

It is advertised to output 1W (1,000mW) of laser radiation at 447nm.

This is the reason I call it a "portable laser" on this website instead of a "pointer". Lasers designated as "pointers" must -- by US law anyway -- have a power output that does not exceed 5mW.

***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 447nm (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!!!

You must also have the appropriate laser safety eyewear and *USE IT* 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!!!
You can't just bop on down to your local Seven-Eleven, Quick-E-Mart, AM/PM, or other similar convenience store for some "Eyeballs-In-a-Can" when you ruin the ones you have. In a few hundred years perhaps, but not now (2011).

It comes in a handsome aluminum body with a dark matte grey finish.

SIZE

To get the laser to turn on, first be certain that the furnished 18650 cell is installed. If there isn't, then install it (see directly below), and THEN you can go set fire to the dead wingless legless fly you found in your box of raisins*...er...uh...go do some "scientifical" experiment.

Aim the laser well-away from your face first.

Press & release the tailcap button to turn the death ray...er...uh...LASER on; do the same thing to deactivate it.

The focus is easily adjustable from just a few millimeters from the exit aperture to infinity by simply rotating the bezel (head). Unlike some other focusable lasers, doing this does not leave the head feeling "wobbly" or loose.

*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 change/charge the battery in your blue laser, unscrew and remove the tailcap, throw it in the {vulgar term for feces}bowl, yank that silver handle on the cistern down, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the used cell out of the barrel and into your hand, and recharge it.

Insert a newly-charged 18650 rechargable Li:ION 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 flush away that tailcap now?

To charge the 18650 cell, place it in the charger, orienting it so its button-end (+) positive is on the bottom (flat-end) of the charger.

Plug the charger into any standard (in north America anyway) two- or three-slot 110 volts to 130 volts AC 60Hz receptacle.

A red light on the charger should now come on; this indicates charging is in progress. When the 18650 cell has reached full charge, the light on the charger 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.

Current usage measures 1,632mA (1.6320 amperes) on my DMM's 4A scale.

This is a self-contained laser , and not a flashlight meant to be carried around, thrashed, trashed, and abused - so I won't try to drown it in the toliet tank, bash it against a steel rod or against a concrete porch, let my mother's big dog's ghost or my sister's kitty cats piddle (uranate) on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a small or 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. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

This is a directly-injected laser though (which by their very nature are more rugged than DPSS lasers!), who's active components are the inverter circuit, 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 deep red (671nm), yellow (593.5nm), green (532nm), and light blue (473nm) laser pointers. 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 deep red, yellow, green, or blue laser beam.

Though you still do not want to intentionally drop your high-powered blue-emitting laser because it's a precision optical instrument.

***EXTREMELY IMPORTANT!!!***
This laser has a very large amount of {vulgar slang term for male nads} to it (measured at 891mW!!!), 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 para los motivos de Cristo (and for heaven sakes and for Pete sakes and for your sakes too) do not shine this laser 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 (whip out) his gun, and hose you down with it.

Waterproofness is as advertised: The tailcap, bezel, and barrel all held a good partial vacuum when they were suctioned (the tailcap held the vacuum even while the switch was actuated a number of times); there are O-rings present at both ends of the barrel as well. After being submerged in the lavatory (bathroom sink) under ~10" (~25.40cm) of water at 82°F (27.80°C) for a couple of minutes (to simulate somebody taking it on a brief underwater junket), nothing untoward happened to it, and no water was found inside when the ends were unscrewed & removed.

I submit this as proof that I really did dredge it.

The biggest downside to this laser is the fact that while this is clearly a CDRH Class IV laser (making it extremely dangerous!!!), there are no safety features at all that are normally required in Class IV lasers; e.g., there is no "emissions" indicator, no startup delay, no interlock of ANY type, and no mechanical beam shutter. This laser behaves like a Class IIIa laser pointer in this regard, which I believe is a rather severe no-no!!!

Having said that, there is something else that pisses me off about this laser.
It's that asinine duty cycle recommendation -- the instructional material states the following (in typical "Chinglish" -- no changes to grammar or syntax were made):

"It is suggested that continuous working time never more than 30 Seconds," {yes, a comma and not a period). No "cooling" (off) period is shown; though I would presume that it would be no less than 1 minute (60 seconds).

Does this eval. look an awful lot like the one I made for this laser?
Thought you'd say so.
That's because they appear to be optically and electrically identical; differing only in case color. So I was able to use its evaluation as a template for this one.

That shiny toridial (doughnut-shaped) thing is the front face of the laser diode.

Beam terminus photograph of this unique (well, "not-so-unique" now) laser on the target at 12".
Beam image bloomed ***SIGNIFICANTLY*** even though it was daylight when the photograph was taken. That white color does not actually exist.
"Not no way, not no how" as they say.

Beam terminus photograph of this laser on the target at 12"; collimating lens removed.

Beam terminus photograph on a wall at ~10'.
Again, that white color does not really exist, and beam image bloomed a bit.

This is a nonsmoking household and nothing was on the stove when this
photograph was taken, so I'm a bit surprised that the camera caught the actual beam.

Stability analsis

Short-term stability analysis for 600 seconds (10 minutes).

I had been running a "testicles to the hard vertical surface" {"balls to the wall"} long-term stability analysis, but the test got queered after the LPM and the computer somehow lost the com link; and seeing how the laser temperature was so high, I decided to not attempt to redo it.

LASER TEMPERATURE CRITICAL...er...uh...I mean Laser temperature was measured with a CEM DT-8810 Noncontact IR Thermometer at 117°F (37.22°C) when the test was 2,455 seconds (24.25 minutes) in progress during the test; which self-terminated shortly thereafter.

In light of this, I have decided to perform narrowband spectroscopy of it to check for wavelength drift; see below for results of this analysis.

Power output measurement

Power output with the collimating lens in place: 690mW.

Power output measurement

Power output with the collimating lens removed: 891mW.
This shows that the lens housing is vignetting (cutting off) the beam; this power differential is far greater than would be caused by merely passing the laser beam through a lens.

Power output measurement

After intentional ignorance of the duty cycle recommendation (powered on for 5 minutes constantly): 817mW.

Spectrographic analysis of the laser diode in this product.
Wavelength appears to be ~445nm, which is ***WELL*** within specification for the type of laser diode used in this laser.

Same as above; but spectrometer's response narrowed to a band between 440nm and 450nm.
This shows that the wavelength is in fact exactly 447.00nm and the spectral line halfwidth is ~2.20nm.

Spectrographic analysis of the laser diode in this product; taken right at lasing threshold.

Spectrographic analysis of the laser diode in this product; taken right at lasing threshold; but spectrometer's response narrowed to a band between 440nm and 450nm.
. This shows that the wavelength is 445.85nm and the spectral line halfwidth is ~1.65nm.

Spectrographic analysis of the laser diode in this product; taken just below lasing threshold.

Same as above taken just below lasing threshold; but spectrometer's response narrowed to a band between 420nm and 470nm.

Spectrographic analysis of the laser diode in this product after five minutes of continuous opertion (intentionally ignoring the duty cycle recommendation of 30 seconds on, 60 seconds off for cooling). Exterior temperature of the laser head after this test was 123°F (50.55C°); ambient temperature was 69°F (20.55C°)

Same as above; but spectrometer's response narrowed to a band between 445nm and 450nm to pinpoint wavelength, which is 447.30nm. Spectral line halfwidth is ~2.20nm.
Wavelength drift was only 0.30nm longer -- somewhat less than expected.

Spectrographic analysis of the laser diode in this product after approx. 25 minutes of continuous operation to check for wavelength drift; spectrometer's response narrowed to a band between 444nm and 449nm to pinpoint wavelength, which is 446.247nm. Spectral line halfwidth is ~1.42nm.

The raw spectrometer data (comma-delimited that can be loaded into Excel) is at http://ledmuseum.candlepower.us/43/445-4.txt.
Wavelength via this file is 446.590nm.

Spectrographic analysis of fluorescence of a uranated* glass marble while being irradiated with this laser.

Spectrographic analysis of the fluorescence of the 2009 NIA Commemorative Insulator in uranated* glass when irradiated with this laser.

*"Uranated" - infused with an oxide anion of uranium, *NOT* piddled (peed) on.
Commonly referred to as "Vaseline glass" because it has
a distinct pale yellow-green color when not being irradiated.

Note spelling: "urAnated", not "urEnated","urInated",
"urOnated", "urUnated", or sometimes "urYnated".

Test unit was purchased from DinoDirect.com on 06-08-11 (or "08 Jun 2011" or even "Jun 08, Twenty Double Sticks" if you prefer) and was received at 3:07pm PDT on 06-28-11 (or "28 Jun 2011" or even "Jun 28, Twenty Double Sticks").

UPDATE: 07-04-11
The "starfield projector" from the Dapper Stage Laser Light Show screws into and fits this laser if the thin white toroidal (doughnut-shaped) "sticker" over the output aperture is removed.

To wit:

This is the laser with the starfield projector affixed to the end.

This is a photograph of but one of many patterns that can be generated.

And this is a video on YourTube showing a holographic starfield projector actually in use on the 1000mW 447nm Waterproof Adjust Focus Blue Laser Pen. The starfield projector from the Dapper Stage Laser Light Show properly fits & screws into the laser aperture -- which does indeed have a female threaded receptacle that this starfield projector fits. The patterns change as I slowly rotate the starfield optic clockwise (as though tightening it) -- it is actually designed to be used in this manner.

That music you hear is the song "The Voice of Energy" by Kraftwerk. This laser is not sound-sensitive; the audio may be ignored or even muted if it pisses you off.

UPDATE: 07-20-11
This is the "sticker" being removed so that the holographic "starfield" projecting heads from other laser products will fit.

PROS:
Color is very radiant & unusual for a handheld laser
The price is right!
Uses a rechargeable power source; never have to purchase disposable batteries for it
Can directly use the "5 in 1" effects head that is commonly found on other lasers
Color is very radiant an unu...o wait, I said that already!!!

CONS:
***SERIOUSLY*** underpowered; it is advertised as being a 1 watt laser
Shorter-than-expected duty cycle recommendation (published at 30 sec. "on"; no "off" time stated).
No safety features required of a CDRH Class IV laser -- this is by far what nocked the most off of its rating!!!
