i am building some bluray lasers, ive got 2*phr-803t 3* dt0811 and 1*lg ggwh20l.
Ive got some axis metal holders and lenses, and various ideas for powering them, but ive not dared extract the ggw-h20l diode until i can be sure about powering and cooling it.
Ive got the tec coolers from a few of those mini fridges, so ive some bits to play with.
for powering i am trying lm317 circuits, but off a 9v battery they dont seem powerfull enough to drive much past 100ma, ive got the psu kit from normand defayette of ebay, and ive found a thing called l200c regulator which looks like a lm317 but has 5 pins and can regulate current and voltage, so that might be a simple solution. Ive also ordered a bench psu with voltage and current controls and 2 big vu style meters so i can be sure not to fry any of the delecate diodes. I hope a bench psu is suitable for testing laser diodes...any one out there use one?
extracting these diodes from the glued metal heatsinks is really scary and difficult, I think the phr803t sleds are more tricky then the dt8011 heatsinks, ive just spent half an hour snipping one out of an 803sled, gonna test it after this writing.
I also have a few laser pointers to dismantle, i got one of ebay for 4 pounds and it registers 140mw on my coherent 210 power meter.
Ive bought a couple of 1w ir 808nm diodes, a c-mount and a to3 and another 500mw 808nm diode from snoctony on ebay in china.
The plan is to make some dpss modules, ive got a few green crystal sets and even a 473nm set to build.
Whats the reason for me telling this...
i guess its just to say hi to the community and to let any experts here know ill be hounding them for advice at some point in the future!
Ive had a nice response from sam at sams laser faqs on a couple of questions i had, so if he ever comes here, then thanks for the info!
any tips on removing these precious little diode components from the glued heatsinks they arrive in?
any chance a dvd rom construction factory would sell them before they get used?
or better still, can anyone think of an easy solution for keeping them in the heatsink and mounting the diodes with a collaminating lense.
can anyone show me what the exact parts in these sleds are?
whats the tiny little optics right infront of the diodes, and what does the little cube do to the beam, does it polarise or just combine the paths of both diodes?
ok , feel free to ask me questions about my adventures in laserland !
ps i can get my phr803 sleds in the uk for about £13 is that a good deal?
whats the going rate for the various diodes?

i never splecheck so ignore any typos!
