Does anyone know if there exists as a LASER or MASER in which
thermally excited atoms lase? If so, at what temperature?

opto-thermoionic referigeration systems if I remember correctly
operateate in the 600C range. I might be wrong but I remember reading
a paper a couple of years ago that described what was basically a
reverse solar panel. The thermoionic effect forces electrons in doped
silicon into higher energy confermation and the silicon dumps the
energy by giving off a photon.
