Hello fellow laser junkies. I finished building this 'labby' a couple weeks ago; figured I'd show it to people that can properly appreciate a bunch of coherent photons and the difficulties involved in producing them (if you're like me, everyone you know thinks you're a just a little too obsessed with lasers... they may be right).
The diode is pressed into the cylindrical heatsink and then another large heatsink is bolted to the back of that; it is a 1/4" thick bar of aluminum the same size as the front panel it is mounted behind. All these parts were lapped and then assembled using a TIM.
The driver is temporarily a ddl based lm350t constant current set for 1250mA. This will be replaced by a Flexmod P3 and a temperature monitoring circuit to keep it living for a long time.
Now for a couple of action shots!
These next ones I decided to set up a quick-and-dirty as it gets interferometer (not a real good laser for the task, but I was bored) Power was reduced to about 250 or 300 mA if IIRC. The laser was defocused a bit, and quite a bit so in the last photo to make for some really big fringes.
Thanks for looking and feel free to leave feedback, the most I get from anyone locally is "Gee... That's neat... What's it for?" Total lack of understanding!:banghead:
