Which outcome results from exceeding gain medium thresholds in excimer lasers?

A)Increased amplified spontaneous emission (ASE)
B)Enhanced pulse duration compression
C)Improved spatial mode purity
D)Reduced optical cavity losses

💡 Explanation

Amplified Spontaneous Emission increases when the laser's gain medium thresholds are exceeded, because a higher population inversion yields increased broadband photons created by spontaneous emission, rather than coherent lasing. therefore ASE is more intense, rather than cavity photons.
