Yesterday I built my first laser- a phr-803t @ 120 ma using a flexdrive. At first it wasn't working but I used new batteries (alkalines ) and it did. After about 5-10 minutes of intermittent use the output dropped dramatically, from a bright dot w/ visible beam in the dark to a barely visible dot at 3 feet. I changed the batteries (more alkalines ), and it stopped working totally. Did I kill my diode somehow? If I did, how? The module has very little heatsinking but it didn't seem to be getting very hot. I'm pretty sure the diode is genuine since it came still in the correct sled, and I got the flexdrive preset.
