LZIR808-200 808nm Infrared Invisible Burning Portable Laser, retail $51.01 (http://lazerer.com...)

Last updated 09-24-13

(In reference to the small box I received from an Ebay seller at 4:44pm PDT on 06-30-11):
{sung like the Foreigner song "Feels Like the First Time"}

The LZIR808-200 808nm Infrared Invisible Burning Portable Laser (hereinafter, probably just called a "NIR portable laser" or even just a "laser") is a NIR (Near-Infrared), directly-injected diode laser. That is, it produces NIR 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 pair of RCR2 rechargeable Li:ION (lithium ion) cells -- you just charge them back up when they poop out...never have to run to the store for batteries. However, if you need the laser *RIGHT NOW* and your RCR2 cells are shot, you can pop in a pair of CR2 disposables and get your laser to function properly that way.

It is advertised to output 200mW of laser radiation at 808nm.

This is the reason I call it a "module" 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.

You must 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 matte black finish.

SIZE

To get the laser to turn on, first be certain that the furnished RCR2 cells are charged and installed. If they aren't, then install them (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 batteries in your NIR 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 cells out of the barrel and into your hand, and recharge them.

Insert two newly-charged RCR2 rechargable Li:ION cells or two CR2 lithium primary (disposable) cells into the barrel, orienting them so that their flat-ends (-) negatives go in 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 RCR2 cells, place them in the charger, orienting them so their nipple-ends (+) positives face on the top of the charger.

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 charger should now come on; this indicates charging is in progress. When the RCR2 cells have reached full charge, the light on the charger will turn from red to green.

At this point, unplug the charger, remove the charged cells from the charging cradle, and install them in the laser as directed above.

Current usage measures 398mA (disposable CR2 cells) and 399mA (rechargeable RCR2 cells) 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.

***EXTREMELY IMPORTANT!!!***
This laser has a fairly large amount of {vulgar slang term for male nads} to it (measured at 338mW!!!) and the beam is nearly invisible to the unaided eye, 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.

The biggest downside to this laser is the fact that while this is clearly a CDRH Class IIIb laser (making it fairly dangerous!!!), there are no safety features at all that are normally required in Class IIIb 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 -- though not as much as the two 445nm blue lasers I recently tested.
It's that duty cycle recommendation -- the instructional material states the following (no changes to grammar or syntax were made):

"Don' t operate it continuously more than 3 minutes every time" {note no period where one would normally go, and note the extra spaces in the word "Don't"). No "cooling" (off) period is shown; though I would presume that it would be no less than 3 minutes (180 seconds).

Spectrographic analysis of the laser diode in this product.
Wavelength appears to be ~808nm, 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 800nm and 820nm.
This shows that the wavelength is in fact 806.01nm and the spectral line halfwidth is ~3.30nm.

Spectrographic analysis of this laser after three minutes of continuous operation.
This shows that the wavelength is now 807.91nm and the spectral line halfwidth is ~2.30nm.

Spectrographic analysis of this laser; newest (01-13-13) spectrometer software settings used. Spectrometer's response narrowed to a band between 800nm and 810nm to pinpoint wavelength, which is 806.040nm.

This is a video showing this laser unsuccessfully attempting to nock the Syma S107G R/C Coaxial Helicopter (Red Canopy) out of the air by irradiating and overloading its IR sensor. When the heli does rapidly lose altitude toward the end of this video, the cause was my mishandling the Tx (transmitter), not the laser.

That music you hear is the song "13" by Anthrax. This laser and heli are not sound-sensitive; the audio may be ignored or even muted if it pisses you off or if you aren't a metalhead and hate this type of music yet still want to see the laser try to shoot down the heli.

Brief video of the LZIR808-200 808nm Infrared Invisible Burning Portable Laser irradiating a piece of GITD (Glow In The Dark) material that's already been "charged" by another source of shortwave visible radiation (~442nm royal blue). Note that the spot brightens significantly; if this were some thin material like GITD paper, you'd almost certainly see a darker area where the laser's NIR (near-infrared) 806nm radiation had been striking it because the GITD properties were depleted in the areas exposed to NIR radiation (at significantly longer wavelengths than the excitation wavelength range).

That music you hear is the song "R2-D2 (Lives in my Butt)" by the Rochester NY. USA comedy punk synth band Worm Quartet. This laser is not sound-sensitive; the audio may be ignored or even muted if it ticks you off.

Laser beam causing higher level of glow in a GITD (Glow In The Dark) glass square; this is why IR radiation depletes GITD faster than having no radiation at all impinging upon it.

Brief video of the LZIR808-200 808nm Infrared Invisible Burning Portable Laser irradiating a piece of GITD (Glow In The Dark) material that's already been "charged" by another source of shortwave visible radiation (~442nm royal blue). Note that the spot brightens significantly and then becomes dimmer than the surrounding area after it moves off. This is because the GITD properties were depleted in the areas exposed to NIR radiation (at significantly longer wavelengths than the excitation wavelength range).

That music you hear is the song "Architect of Fear Intro" by...guess who it is...come on, I know you know this one...

If you guessed Hozay Feliaciano then ¡¡¡PARA NO DE LOS MOTIVOS DE CRISTO!!! It's Raven, you silly goose!!! "Raven" the NWOBHM (New Wave Of British Heavy Metal), not Raven Symoan or however the F you spell the douche's name. This laser is not sound-sensitive; the audio may be ignored or even muted if it pisses you off.

Darker spots in a GITD sheet; these are where it was irradiated with this laser.

Stability analyses of the LZIR808-200 808nm Infrared Invisible Burning Portable Laser, first shown irradiating the sensor of the USB2000 Spectrometer for three minutes (where you can see the wavelength lengthen slightly), then irradiating the photoreactive region of a Pocket View-It® IR Detector Card with anti-Stokes phosphor that requires no optical "charging" prior to irradiation (where you can see the color change) and does not "poop out" with prolonged exposure. Finally, there is a graph produced by the LaserBee 2.5W USB Laser Power Meter w/Thermopile over a period of 3:30 that shows no power degradation. So I'm still uncertain as to why the color on the IR detector changes (this is definitely repeatable; it isn't just a one-time fluke).

That music you hear is the song "Harms Way" by...o I know you've got to know this one...take a whack at it anyway...

...if you guessed Hozay Feliciano, ¡¡¡PARA NO DE LOS MOTIVOS DE PETE!!!
It's Anthrax you silly goose!!!

This laser is not sound-sensitive; the audio may be ignored or even muted if it tees you off or if you aren't a metalhead. I added "***NSFYE!!!***" (Not Safe For Your Ears) to the title because not everybody who watches boring laser vidz on YouTube is a metalhead.

TEST NOTES:
Test unit was purchased on Ebay on 06-10-11 (or "10 Jun 2011" or even "Jun 10, Twenty Double Sticks" if you prefer) and was received at 4:44pm PDT on 06-30-11 (or "30 Jun 2011" or even "Jun 30, Twenty Double Sticks").

It actually came on the 29th, but I was not home to sign for the parcel so a "We Re-Deliver" notice was left in my incoming mail receptacle.

UPDATE: 00-00-00

PROS:
Powerful enough to burn, destroy, and leave wrink...O WAIT!!! WRONG INFOMERCIAL!!!

Beam spot is *SLIGHTLY* visible, and will register rather strongly on many digital cameras
Can use both primary (disposable) CR2 cells and secondary (rechargeable) RCR2 cells
Labelled properly for both wavelength and approx. power output

CONS:
No safety features required on a CDRH Class IIIb laser in the United States (this is what nocked the most stars off its rating!)
Has a somewhat "chintzy" feel to it
Really sticky, nasty "goop" is present on the bezel threads
