← ScienceWhich outcome results when optical pumping ceases in a laser?
A)Polarization diminishes, gain decreases✓
B)Population inversion increases sharply
C)Cavitation leads to energy loss
D)Frequency doubles within crystal lattice
💡 Explanation
When optical pumping stops, the process of stimulated emission decays because the required population inversion is no longer maintained; therefore the degree of polarization reduces, gain decreases, rather than the other effects which require steady state conditions.
