This is a green-emitting DPSS (Diode-Pumped Solid State) laser module -- that is, you connect it to any source of +3.0 to +5.0 volts DC and are instantly rewarded with a nice green laser beam.
It's rated to produce 5mW of laser radiation at 532nm in the green part of the spectrum (these values were measured at 8mW with a
wavelength of 532.010nm).
This is part # DGM512-D001 on Instapark's website.
Because this is a laser, you should not shine it into your eyes, other people's eyes, pet's eyes, etc. Just use a little common sense here, k?
To use your shiny new DPSS 532nm Green Diode Laser Module, just feed it anywhere from +3.0 volts to +5.0 volts DC from any convenient source (see directly below).
This portable laser requires a source of +3.0 to +5.0 volts DC, whether that comes from two or three 1.5 volt cells in series or an AC power supply. Therefore, I do not have to tell you which part to remove, kick down the basement stairs into that dark little room crawling with thousands of hungry silverfish with full pissinary bladders, and then rather emphatically tell you not to.
Connect it to power -- this could be two or three AA cells connected in series, a product like the Aixiz Diode Laser PSU, or even a lithium-ion 18650 cell like the type that powers the 2 Watt S3 Spyder Arctic G2 445nm Blue Laser w/SmartSwitch™, and a greeen laser beam should be generated.
As usual, red wire is (+) positive and black wire is (-) negative.
If you wish to have a power (on/off) switch, you'll have to procure & install it yourself. The two wires on the switch go to the laser module's red wire and the battery (+) positive.
My Aixiz Diode Laser PSU was used to power the laser module for all of the measurements, analyses, and beam photographs present on this web page.
The DPSS 532nm Green Diode Laser Module is not water-resistant or submersible (it's a laser module for Christ sakes!!!), so please keep it away from water.
And since this is a laser and not a flashlight, the usual assortment of potentially damaging or even destructive tests will not be performed on it...lasers are meant to be loved, not punished.
Operating temperature range (ambient temp.) is stated as 20°C (68°F) to 30°C (86°F)
The beam emerges from this laser in TEM00 (Transverse Electromagntic Mode 00); that is, it has a true Gaussian power distribution with a bright hotspot smoothly falling off to extinction at its edges.
Most DPSS green lasers are TEM00 though, so no big surprise there.
Tops out at 8mW on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.
Beam photograph on the test target at 12".
Beam photograph on a wall at ~15 feet.
In both of these photographs, that white color you see doesn't exist in the actual laser's beam; the beam image bloomed rather significantly in the lower photo.
Spectrographic analysis of this laser.
Spectrographic analysis of this laser; spectrometer's response narrowed to a range between 530nm and 540nm to pinpoint wavelength, which is 532.010nm.
Spectrographic analysis of this laser; spectrometer's response narrowed to a range between 800nm and 820nm to pinpoint pump diode's wavelength, which is 810.610nm.

A beam cross-sectional analysis would normally appear here, but the computer that hosted the ProMetric 8 Beam Cross-Sectional Analyser was destroyed by a lightning strike in July 2013 (the monitor had this big-ass hole blown right through its viewscreen); although a replacement computer is already en route (it just came several days ago actually), there's a fairly significant chance that the beam cross-sectional analyser itself was also taken out because both the computer & test instrument shared the AC power at the same outlet on the same power strip.
Test unit was purchased on Ebay on 11-13-13 (I had purchased a 515nm directly-injected green laser, but this one was sent in error), and was received on 11-18-13.
Beam is clean with no unwanted artifacts or speckling in it
The driver circuit gets unexpectedly warm rather quickly
