Hi PL
I have an old 532nm DPSS laser with a complex history that I brought with me from the UK and it does about 60mW now. I'm not sure what mWatts it used to do or what it could do if it were refurbished.
Power supply..
Driver (TTL I believe)...
Module
Module cover off showing wires to the single TEC sandwiched in the module...
Any ideas what it might be or any suggestions on what to do with it?
