The PGL RG Portable Laser is quite unusual as far as portable lasers go.

Not only can it produce a green beam, it can produce a red beam and even a yellow beam (by having both the red & green lasers on simultaneously)!

Before you fire up this studly laser, lock the kids upstairs and put out the dog...hmmm...locking the children in ***ANY*** room isn't a very good idea, and putting out the dog would also be a poor idea because it isn't on fire...but you know what I mean!

It comes in a rather beefy aluminum body with what I believe is a baked enamel finish (colored black), and feeds its two laser diodes with a single 18650 Li:ION rechargeable cell.

I cannot verify the finish, as the testing method I use could (well, probably ***WILL***) damage the finish, and this laser does not belong to me.

To use your PGL RG Portable Laser, please be certain that the 18650 Li:ION cell is installed (see directly below), and THEN you can go liven up that dull, boring party.

Before your first use, remove that blue plastic disc from the laser aperture (beam opening); that is there to protect the optics from dirt, dust rabbits, or whatever other unwanted material might find its way in there during shipment.

Press the tailcap button firmly until it clicks, and then release it.

To energise the green beam, gently press & release that green button on the barrel.
To energise the red beam, do the same thing again.
To turn both lasers on at once (which will result in a yellowish-green beam terminus spot), do the same thing a third time.
To turn the beams off, do the same thing a fourth time.

Just like it reads on the backs of many shampoo bottles, "lather, rinse, repeat." In other words, pressing the blue button a fifth time starts the sequence all over again, beginning with the green laser.

To neutralise the laser (disabling the blue pushbutton), simply press the tailcap button firmly until it clicks, and then release it.

To change the battery in your shiny new (or corroded old

) PGL RG Portable Laser, 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 dustcart (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 recharge it, Do not dispose of or recycle it; and for God sakes please do not throw it into a trout-filled stream!!!

Insert a new 18650 Li:ION rechargeable 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:
Green: 868mA

This is a portable laser, 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 carport 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, her kitties, my kitty or my sister's kitty cat piddle (uranate) on it, hose it down with my mother's gun, run over it with a 450lb Quickie Pulse 6 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 (now 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 also a loaned item*, so I would have not performed any potentially damaging or even destructive tests on it regardless of what type of product it was.

One thing that really pisses me off about this laser is that it has a totally asinine duty cycle recommendation -- the "ON" time is just 45 seconds to 1 minute max!!!
This is just preposterous for a portable laser in such a heavy aluminum body.

Beam image bloomed ***SIGNIFICANTLY***, white color does not exist, and those green "splotches" are camera artifacts which do not exist in the actual beam.

Room illuminated only by the green laser being directed at the ceiling almost directly above the camera.

Spectrographic analysis

Red laser only (PRE-FAILURE!!!). Tops out at 160mW.

Power output analysis

Green laser only. Tops out at 150mW.

Power output analysis

Green laser only (newer power output anaysis). Tops out at 152mW.

There is no reading for "both red & green" because the red laser is nonfunctional (only the green came back online when repairs were attempted).

Power output analyses were performed on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.

Spectrographic analysis of the red laser in this product.

Spectrographic analysis of the red laser in this product; spectrometer's response narrowed to a range between 650nm and 670nm to pinpoint peak wavelength, which is 662.956nm.

Spectrographic analysis of the green laser in this product.

Spectrographic analysis of the green laser in this product; spectrometer's response narrowed to a range between 528nm and 538nm to pinpoint peak wavelength, which is 531.328nm.

TEST NOTES:
Test unit was loaned to me (shipped to me directly from CNI) by M.H. on 08-13-12.
Since it failed early during testing (and my subsequent repair attempts made with his permission were marginal at best and only restored partial operation), he has indicated to me that he no longer needs it returned.

It emitted a fairly large quantity of very acrid smoke when the tailcap was removed shortly after having spectrographic analyses of it; the repairs I later attempted revealed a rather large cinder from what I believe was an SMD power resistor on the PCB (printed circuit board); the heat from this suspected resistor becoming a "krispy kritter" even melted the insulation on one of the thick laser diode power leads.

* See directly above; CNI has expressed no desire to repair this laser, and M.H. doesn't want to bother with all the time & money of shipping it back and forth, so if I am not able to repair it to at least moderate functionality (insomuch as the red & green lasers are functional and individually addressable), I need not return it.

UPDATE: 00-00-00

PROS:
Very unique as far as portable lasers go

CONS:
Some chromatic abberation is present
Some safety features mandated for a CDRH Class IIIb laser are missing (this is what lopped off ½ star)
Totally bogus duty cycle -- that's what nocked off the rest of the stars!
