Hey guys.
For any of you guys out here who aren't just interested in laser pointers or handheld lasers, what kind of advanced cooling system do you guys use?
Heatsink with fan seems to work for several mW lasers which aren't meant to run for a "long" time.
I want to make one of those knife edge array builds with DTR's 3.5W 450nm NDB7A75 diodes and see how bright I can get.
Each diode costs about $195 (this hobby hates my wallet) so I definitely wouldn't want to take any risks and provide them with the proper cooling they need.
Though I have had few laser projectors and maintained them and replaced broken parts over the years, I'm still not very experienced with electronics (or thermodynamics).
I know commercial laser modules and some custom builds use TEC coolers.
How do you use and control the TEC coolers?
Here's what I currently have in mind for a home-use diode array TEC cooling:
TEC cooler/heatsink/fan sandwich, TEC controlled with thermistor and a PID controller.
Is this a decent annd economical way to do it?
How would you set it up yourself?
