The discussion centers on the feasibility of creating a resonant chamber within the chromosphere of the sun using two mirrors, one of which is half-silvered, to potentially produce laser radiation. Participants question the conditions necessary for achieving population inversion, emphasizing that excitation likely occurs through heat rather than through mechanisms conducive to laser action. The conversation highlights the significant length of approximately 3000 km that can be traversed within the chromosphere, suggesting that even without mirrors, the conditions for stimulated emission may exist over short time scales.
