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.
