← ScienceWhich consequence results when a laser suffers catastrophic optical mirror damage?
A)Gain medium thermal runaway accelerates✓
B)Population inversion spontaneously ceases
C)Coherent photon emission reverses polarity
D)Stimulated emission cascade becomes suppressed
💡 Explanation
Reduced reflection from the mirrors raises the energy density within the gain medium; the resulting absorption leads to thermal runaway because non-radiative relaxation processes convert this energy into heat. Therefore the gain medium overheats, rather than disrupting the population inversion directly or reversing the light polarity.
