← ScienceWhich risk increases when a pulsed laser with variable cavity capacitance emits broadband radiation?
A)Gain medium thermal lensing✓
B)Increased spontaneous emission rate
C)Mirror delamination due to CTE mismatch
D)Population inversion saturation rate
💡 Explanation
Increased energy fluctuation causes gain medium thermal gradients because capacitance variations alter the pulse energy stability. Therefore, thermal lensing increases, rather than spontaneous emission changes which happen at atomic levels under different pumping conditions.
