I'm intending to buy a 5mW 532nm laser diode to use in pretty small housing(unconventional, not at all like a pointer), but all the ones I've seen for a reasonable price require 3V to function. Should I just buy a laser pointer, dissect it, and use the power supply from it, or is there a better way?
For that matter, will a simple 3V watch battery work for this purpose? How would I go about powering the diode with it?
