← ScienceWhich mechanism limits stimulated emission efficiency within excimer lasers?
A)Rapid spontaneous decay of excited dimers✓
B)Increased resonant energy transfer efficiency
C)Enhanced population inversion characteristics
D)Suppressed amplified spontaneous emission threshold
💡 Explanation
Rapid spontaneous decay limits laser efficiency because spontaneous emission removes excited dimers non-radiatively, reducing population inversion via increased non-stimulated decay rather than stimulated emission. Therefore, output intensity is capped due to limited excimer population rather than amplified emissions.
