← ScienceWhich consequence results when thermally-induced birefringence instability in a high-power laser system exceeds compensation?
A)Beam depolarization increases significantly✓
B)Wavelength doubles within cavity
C)Spontaneous emission is suppressed
D)Gain medium reaches transparency
💡 Explanation
Increased internal stresses cause depolarization because thermally-induced birefringence modifies polarization states across the beam's profile, initiating beam distortions; therefore, depolarization increases, rather than harmonic generation or gain medium changes under thermal loads.
