Hello, i was wondering if anyone could tell me or show me to a guide that would explain what different components are in a laser. Basically i am trying to build a >120 mw red laser. i have very little clue were to buy the right boards and diodes and housings. I cant seem to find anything on the forum search or google. Thank a lot guys. Also the laser does not need to be hand held. i would actually prefer a non-hand held laser. Thanks again you all.
