I am working on laser engraver system with couple of my friends . I extracted a laser diode from a 16X dvd writer , and built a Lm317 laser driver , I am building my own laser aixiz module .
My questions are :
what is the focal length of the dvd lens so I can determine the beam diameter for the control system part ?
is there any way to build a ttl laser driver ?
