Hello,
This is my first thread and it's been about a month since i've started to take interest in lasers.
Well I've bought 3 2dollar keychain lasers for some taking-apart, and i've noticed they had no "diode" in them. At the place where there is supposed to be a diode, there is a flat chip with something tiny sticking out of it.
what do these lasers use to make the laser without having a diode?
