I am building a new cryogenic laser and rather than bury progress reports within another thread, I am posting a link to a few images of the low temperature insert that I finished earlier today. I am working on the RT optical bench that will combine the output of the two diodes and focus them into an SMA fiber for convenient coupling into a laser projector.
Let me know what you think.
