I'm new to lasers, but have pretty much experience with electronics and homemade circuits. I actually use the LM317 to make some custom power supplies, so I already had the parts I need for the DDL driver.
I salvaged an 0811 diode from a broken HD-DVD player, and bought a glass lens from eBay. I can't get the diode to lase even when I have the pot at its lowest resistance. I've tried a homemade 7.2V pack as well as a 9v battery, and I still get the same thing. The circuit works fine when I use LEDs with it.
Any ideas?
