OK, I have a wierd problem, or I've neglected to read something crucial. I've built my driver circuit, and it tests out perfect, however, it does not seem to want to actually drive a laser to a high enough voltage to actually burn anything. I've tried on two diodes, and two different driver boards. in each case with the same results. it started out fairly bright, but still not very hot, the light just got sligtly warm. Then after a bit, it gets dim, and remains that way. It still responds when I turn the pot, but it just doesn't get too bright.
I feel like I'm missing something.
Can anyone give me a clue here?
What to check, what to change? what to test?
Thanks.
Rich
