OXLasers CB-1000 445nm Blue Portable Laser Focusable Waterproof, retail $185.00 (www.oxlasers.com...)
Manufactured by: OXLasers China (www.oxlasers.com)
Last updated 12-07-11

(In reference to the small box I received from an Ebay seller at 2:22pm PDT on 06-27-11):
{sung like the Foreigner song "Feels Like the First Time"}

The CB-1000 445nm Blue Portable Laser Focusable Waterproof (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 445nm.

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.
Yet the storage box it comes in has the phrase "Laser pointer" in large gold font on its upper surface.

The USS Lantree is a quarantined vessel by order of Starfleet Command.
Do not board.

...o wait, wrong warning!!!

This laser can produce up to 1 watt of laser radiation at 441nm (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.


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 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 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 1,472mA (1.4720 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 cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata 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 cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata 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.

This laser has a very large amount of {vulgar slang term for male nads} to it (measured at 832mW!!!), 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.
So if it falls into water or if you have a case of coffee penus and you subsequently pyst all over it, just take the garden hose to it or douche it off under the faucet -- good as new!

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).

Photograph of the "business-end" with the collimating ass'y removed.
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.

Beam photograph with laser itself positioned approx. 9 feet downrange.

Power output measurement
Power output with the collimating lens in place: 619mW.

Power output measurement
Power output with the collimating lens removed: 832mW.
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.

Spectrographic analysis
Spectrographic analysis of the laser diode in this product.
Wavelength appears to be ~444nm, which is ***WELL*** within specification for the type of laser diode used in this laser.

Spectrographic analysis
Same as above; but spectrometer's response narrowed to a band between 400nm and 410nm.
This shows that the wavelength is in fact 441.60nm and the spectral line halfwidth is ~2.0nm.

Spectrographic analysis
Spectrographic analysis of phosphorescence of the 405nm Violet Laser Phosphor Target while being irradiated with this laser.

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

Spectrographic analysis
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".

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.

This is a video showing the holographic starfield projector actually in use on this laser. 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.

Test unit was purchased on Ebay on 06-07-11 (or "07 Jun 2011" or even "Jun 07, Twenty Double Sticks" if you prefer) and was received at 2:22pm PDT on 06-27-11 (or "27 Jun 2011" or even "Jun 27, Twenty Double Sticks").

UPDATE: 08-02-11
I found a message (to me of course!) from the seller on Ebay that read:

Hi thanks again for purchasing from us. Free feel to visit our web page to check out more laser for extremly low price. It will be cheaper then you purchase from us on ebay since we don't have to pay for ebay fee. This is our website. Enjoy your surfing!

This website then "turns into" http://lazerer.com, which is a laser source that I really do trust.

UPDATE: 01-15-12
I have given this laser to my very great friends P. Buff and P. Dexter as a belated Christmas present. They knew going in that it was used, so no surprises for them will occur down the road. And I also gave them a rather stern lecture (and several reiterationas along the way) about not using the laser as a pet toy and never attempting to hose down any type of aircraft with it!!!

Since I no longer have it (I gave them the laser itself, the battery, and the charger), that dreadful "" icon will be appended to its listings on this website, denoting the fact that I no longer have it in my custody for additional comparisons or analyses.

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!!!

***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!!!
