(In reference to the large envelope I received from AixiZ Service & Int'l. Inc. at 4:09pm PST on 02-19-11):
{sung like the Foreigner song "Feels Like the First Time"}

This is a laser show unit that features a bright green laser, and two ways to get patterns projected on your walls, ceiling, or other light-colored surface -- it can also project an ordinary dot like a standard laser pointer -- though this product is too powerful to call a "pointer".

It can project a "starfield" that's easily user-adjustable (for the number of and general position of "stars"), project an oval shape that is easily varied by shaking the product (see videos below), and project a rather ordinary "laser pointer-style" dot.

It comes in an easy-to-hold plastic body, and feeds from two AAA cells.

SIZE

Feed the Dapper Stage Laser Light Show a pair of AAA cells (see below), and THEN you'll be ready to hose down that miscreant bass guitarist with green laser radiation!!!*

As you're holding the unit so that the metal thing faces forward and the green trim is on top, rotate that thumbwheel at the top righthand side of the product back toward you. This engages the "starfield" generator. Press and hold down the large black button you see in the center of that green trim. The laser will ramp up to full power within a period of approximately 1,000ms (1 second), and (of course) you'll see stars. Not "see stars" like you've just been socked in the head, but green "stars" as projected by this product. You can then change the number of and general position of the "stars" by rotating the knurled (texturised) portion of that chrome-colored thing on the front of the unit clockwise (as though tightening it). Release the black button to turn the unit off.

To project a simple, single laser dot, turn that knurled chrome-colored thing counterclockwise (as though unscrewing it) until it comes off. Place it somewhere safe. Now, press and hold in that black button, and you'll get your laser dot.

To project polytrophic** patterns, turn that ribbed thumbwheel at the top righthand side of the product away from you (forward), press & hold the large black button down, direct (aim) the unit in the general area you want the projection to occur, and shake the living tweedle out of it. Actually, you need not shake it so hard that the "tweedle" falls off

; just shake it with signifiantly less vigour that you might use when shaking an aerosol bomb (spray can) -- but use shorter strokes so that you can keep the laser beam aimed where you want it to be. You can shake it side-to-side, or use a somewhat circular motion -- if a certain method of "product shakeage" results in a pattern you particularly like, you can always shake it that way.

When shaken in this manner, you'll get all kinds of nifty patterns based on an oval -- the oval is the basic pattern generated by the type of scanner inside, but when the X- and Y-axes are varied and the unit's aim is physically changed, you get a lot more than just a plain old ordinary old oval.

When finished, release pressure on the black button to turn the unit off.

To change the batteries in this laser, slide the battery door off, and set it aside.

Remove the used AAA cells out of the compartment, and dispose of, recycle, or recharge them as you see fit. Please do not under any circumstances flush them down a toliet or throw them into a salmon-filled stream or those tree-huggers might hunt you down and then hug you to death!!!

Insert two new AAA cells into the battery compartment, orienting them so that their flat-ends (-) negatives face the springs for them in each chamber.

Slide the battery door back on, and be done with it.

Unable to measure current usage due to how the product was constructed.

This is a laser show device, 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 the concrete floor of a patio, let my housemate's citty kats

go to the litterbox on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a large claw hammer in order to smash it open to check it for candiosity, fire it from the cannoñata (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, with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannoñata is only used to shoot piñatas to piñata parties away from picturesque 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 a bit more bare than this section of the web page on a page about a flashlight.

Besides, lasers are meant to be loved, not punished.

Green diode lasers are a lot different than those common red lasers you see all the time.

In a 640nm red laser module, there's a red-emitting diode and a lens to collimate (focus) the beam.

In a 532nm green laser (module or larger size), there's a BIG infrared laser diode that generates laser light at 808nm, this is fired into a crystal containing the rare-earth element "neodymium". This crystal takes the 808nm infrared light and lases at 1064nm (yes, deeper in the infrared!). This 1064nm laser light comes out of the NdYV04 (neodymium yttrium vanadium oxide) crystal and is then shot into a second crystal (containing potassium, titanium, & phosphorus, usually called KTP) that doubles the frequency to 532nm - the bright green color you see. This light is then collimated (focused) by a lens and emerges out the laser's "business end". Just before the lens, there's a filter that removes any stray IR (infrared) rays from the pump diode and the neodymium crystal. You don't want that stuff in your green beam, trust me. :-)

This is why green diode lasers are so much more expensive than red ones. Lots of itty bitty parts, and they all need to be aligned by hand. If the polarisation is "off", one or both crystals need to be turned. With red diode lasers, you just slap in the diode and slap a lens in front of it.

This laser is not water-resistant, so please be extra careful when using it around sinks, tubs, toliets, fishtanks, pet water bowls, or other places where water or water-like liquids might be found. And you'll probably want to cover it up or otherwise get rid of it (such as by putting it in a pocket or bag) if you need to carry it in rainy or snowy weather.

VERY IMPORTANT!!! This laser is NOT a toy, and you MUST NOT 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 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 or she turns out to be a police officer, he/she may think he's being targeted, unholster (pull out) his/her gun, and hose you down with it.

One thing that kinda pisses me off about the Dapper Stage Laser Light Show is that the battery door comes off way too easily -- just the act of shaking the product to produce those polytrophic** patterns is frequently sufficient to dislodge it.

Measures 20.0250mW on a Sper Scientific Pocket Laser Power Meter # 840011.
Remeasured (with known-brand-spanken-new AAA cells) at 32.715mW.

Power output measurement

Power output peaks at 13mW.
This test was performed beaming the laser through the scanner ass'y; I no longer get a full-output beam through the starfield projector portion because the mechanism that switches between the two has partially failed; e.g. you get the starfield *PLUS* part of the lissajous projector (fuzzy and to the far right) as the following photograph indicates:

Batteries for this analysis were purchased just before the test.

The last power output analysis (the one with the graph shown directly above) was conducted on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.

TEST NOTES:
Test unit was purchased on Ebay on 02-17-11 (or "17 Feb 2011" or even "Feb 17 Twenty Double Sticks" if you prefer) and was received at 4:09pm PST on 02-19-11 (or "19 Feb 2011" or even "Feb 19 Twenty Double Sticks").

* You must never, ever, I mean ***NOT EVER!!!*** shoot a person with this laser -- or any other laser for that matter!!!

** Product is advertised as having a "polytrophic" scanner; yet when I attempted to look up the definition of that word, nothing at all pertinent to lasers or beam scanning came up.

UPDATE: 02-22-11
The CDRH-mandated "Warning -- Laser Radiation is Emitted from this Aperture" label is not present on this laser or in/on its packaging materials.

UPDATE: 02-22-11
No, you aren't seeing things.
Yes, a same-day update.
The loose battery door has officially been reported as extremely likely to be a fluke affecting only this particular unit; the product's rating will increase and it will receive placement in this website's "Trophy Case" as a result of these findings.

UPDATE: 07-04-11
The "starfield projector" from this unit screws into and fits the 1000mW 447nm Waterproof Adjust Focus Blue Laser Pen if the thin white toroidal (doughnut-shaped) "sticker" over the output aperture of that laser is removed.

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.

This is a video showing a holographic starfield projector actually in use on the OXLasers CB-1000 445nm Blue Laser Module Focusable Waterproof. 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 "Cupajoe" by Anthrax. This laser is 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 'starfield" effect presented herein.

UPDATE: 07-17-12
This product has ***PARTIALLY*** failed; though the lissajous scanner functions properly, the starfield projector does not -- part of the lissajous scan appears to the right (out of focus as well) inside the starfield.

Therefore, that dreadful "

" icon will be appended to its listings on this website, denoting the fact the the product has partially failed but that at least one of its operational modes still functions properly.

PROS:
Unique -- at least I've never seen a similar product
Uses batteries that are common and relatively inexpen$ive
Laser ramps up in power over ~1 second instead of just instantly coming on at maximum power

CONS:
Not waterproof or submersible - but most lasers aren't. Will not figure into my rating
More delicate than directly-injected diode lasers. Again, will not figure into my rating
CDRH-madated laser warning label is not present
Battery door comes off during use surprisingly easily -- that's what whacked that last star off (see 02-22-11 update for important info. regarding this!!!)
