Dissection of GLP

Here is the complete sequence of photos of the dissection of a 532 nm green laser pointer. Since no green direct injection laser diodes are currently available, these pointers are based on the use of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology. A high power IR laser diode at 808 nm pumps a tiny block of Nd:YVO4 generating light at 1,064 nm which feeds a KTP intracavity frequency doubler crystal to produce the green beam at 532 nm. See the Diode Lasers chapter of Sam's Laser FAQ for more information on DPSSFD lasers.
If all you are interested in is what's inside a much simpler red laser pointer, go to the Assorted Diode Lasers Gallery wing and check out the photos there.

I hope that the SPCL (Society for the Prevention of Cruelty to Lasers) doesn't hear about this. It would probably be a good idea to have some tissues handy - some of the pics are quite gory. The pointer was still alive at the beginning of this process and while no critical organs were damaged by the abuse, it will never likely be quite the same even with generous use of duct tape and baling wire. :)

For a less gory procedure (reversible, at least in principle) that should work with minor modifications for several models of green laser pointers, see the chapter: SS Laser Testing, Adjustment, Repair of Sam's Laser FAQ (section: "Disassembling a Green DPSS Laser Pointer"). That unit uses an identical DPSS laser module as this one.
