So I've been experimenting with lasers and I am wanting to build my own. So from my understanding. You have a laser Diode. Which is wired to a voltage regulator or voltage converter. Something to bring the voltage to match the specs of the diode. Which is then behind a lens at the correct focal distance. Then obviously a switch.
I also understand from the dissection of my green laser, that the diode is not a 532nm, but is an infrared diode which is somehow passed through a filter which converts it into 532nm. 532nm diodes don't exist. 520nm ones do however.
So If I where to purchase lets say an Oclaro https://www.ebay.com/itm/Oclaro-HL6...0570?_trksid=p2349526.m4383.l4275.c1#viTabs_0HL63193MG 638nm 700mW Diode.
Wire it to a voltage step down converter which is powered by an 18650. Bring the voltage down to around 2.3v and wire it to the diode. Would it work? Then obviously finding a way to mount it behind a laser lens at the correct focal length.
I also know that diodes get hot and must be installed onto something to wick the heat away.
Also do you need different lenses for different colored diodes?
I would really appreciate it if someone could clarify if any of the above is wrong or add onto it.
