thats too bad. you should have just explained how it could be done. i have redone a few cheap green pointers and realigned the crystals to make a better beam.
but its deff not a good first diy type laser.
and he may have thought you just needed a green diode
Jayrob has a DIY green kit but you dont buy crystals and crap you just use a green module from o like i think and put it in a heatsink inside a cree host
