"so there's a peltier cooler underneath the platform holding the lasers and first optical stage so that the optic can electrically heat or cool the lasers to keep them at the right temperature! "

I get that Peltier coolers are simple, solid state devices, but still. Between that and the prisms and lenses, the amount of complexity here is mind blowing.




I'd expect that sentence to come from a hard sci-fi novel about weapons on an orbital platform or something. Instead, it's a pinky-sized bit of tech working to send cat videos to our phones. Amazing!
