oh, thats a great idea!
i have some burnt identical LDs, and still didnt have the idea to use one of them in a new driver!
thank you, you just saved many LDs lives, perhaps!
if we are talking about high powered reds, they have ridiculously large dies. one day i will have to get some of them extracted.. they are millimeters long, not the grain of sand in others! isnt that absolutely amazing?!? (okay, i never ever found anyone in real live sharing my enthusiasm yet neither.. hehe)
edit, 5 sec after i posted:
they, the large dies, may be in similar size to 808nm dies.. practising soldering *big* and cheap diodes, anyone?
look up die4lasers, he writes how to do it.. sounds doable!
