Hello, this is my first, and likely one of my only threads.
I come to you from a laser forum, looking for a method for closed-loop cooling, to super cool a laser diode.
The basics.
I want a copper block, with two tunnels drilled out that will connect to a continuous loop of super-cooling liquid. In this copper block, the laser will be mounted. though perhaps I will simply line this block with indium foil, and mount the laser to it. Either way, that's neither here nor there.
I originally planned on using LN2, though I read the pressure to liquefy the LN2 as it cycles through, would be immense.
Also, condensation here is not an issue, I can have water drip off this thing all day long, I could care less. The laser itself will be protected, so if the cooler itself gets wet, no biggie.
That's really all of it. If you have any ideas, let me know. I'd like to get <100C if possible. I've seen -191C from a LN2 setup, but it was from a gentleman pouring the LN2 onto the laser basically. I'd like a more elegant design if possible.
