← ScienceWhich consequence results when inconsistencies broaden laser cavities?
A)Spatial hole burning increases efficiency
B)Stimulated emission gains coherence
C)Transverse mode instability proliferates✓
D)Free spectral range maintains accuracy
💡 Explanation
Transverse mode instability proliferates because increased cavity inconsistencies promote **destructive interference** between modes generated within, decreasing stability rather than enhancing stimulation; therefore instability rises rather than efficiency because the coherence threshold reduces amplification.
