Hi all. Since I am new here, I thought I'd post a little about myself.
I work as a researcher at a university doing solar cell research. We use lots of lasers, and just recently wanted to add one as a thickness monitor. So, I was looking for a good blue laser diode. Thor labs and digikey wanted over a thousand, and that would have broken our research budget! I stumbled on this site about two months ago and have been stuck since!
Too much a laser geek, I guess.
My first laser exposure was with cheap laser pointers. Then, I took some optics courses as an undergraduate. Did the typical interferometer labs, etc. Then, as a graduate student I worked with an Coherent Ar+ Innova laser, doing 15W CW. Pumping a TiSaphire. Now I play with Krypton, HeNe, Argon, NiYag, and some others. I think laser diodes are really neat.
I've purchased a few PHR 803T, but since I need a photodiode on die, I think the PS3 diode will work better. Nobody here seams to care about the stability of their power (within reason) as long as it is bigger than the next guys! : I don't really care if mine is 5mW, but I need the power to be really stable. If anybody has a driver that incorporates feedback, PM me. Hopefully I'll have some pictures of the build to show soon.
