Room temperature Orange Laser Diodes

Thanks for the extra info Steve. I'm hoping for more development on the <600nm part of the spectrum.

A 600nm emitting semiconductor laser for only 5$?!

Until one of thsee oranges materializes sub 100$ I'll likely never see coherent monochromatic orange irl. Unless.....I remember seeing awhile back someone post a link to these super compact peltier tec rrings that fit into a larger host. Has anyone tried putting a red onto a tec to shift the wavelength? Another idea I had would be to make a chamber out of the host that holds liquid nitrogen with a quartz window with the tec placed behind the chamber to allow the beam to pass? Just curious ideas I had and thought I'd ask. I do have one that I found in some scrapped gear but I've never played around with a peltier device before and kinda forgot about it.
