Chromosphere population inversion?

    Assuming you could put two mirrors (one half-silvered) into the chromosphere, stationary, without them vaporizing/warping..., could they form a resonant chamber and produce laser radiation?

    Interesting. Can you elaborate on what makes you think this is possible? What would you be stimulating to emit the light?

    I would expect that the excitation happens via heat, in that case I would not expect a population inversion.

    Another interesting thing: As a rough estimate, you can draw a straight line of ~3000km length through the chromosphere (nearly parallel to the surface of the sun). For the time-scale of 10ms and an area density of O(g/cm^2), you already have this situation without mirrors.
