I'm going to be building a laser very similar to this (basically just a different heatsink) What do you recommend as duty cycle for this? I really don't want to kill my diode.
Also, how do you blow a diode by not replacing the lense?
Lud was pretty spot on, the lens just basically melts under the heat causing it to reflect more light back into the diode degrading it quickly.
As for a duty cycle it does heat up pretty quick, I'd go with something along the lines of 20-30 seconds, when you get the laser and turn it on hold it until it feels warm to the touch, that's normally when I I'd turn it off and let it cool for a while.
