Which effect accompanies exceeding the gain medium's amplification limit in a pulsed laser?

A)Stimulated emission dominates spontaneous emission
B)Laser spiking leads to reduced stability
C)Etalon effects initiate mode locking
D)Q-switching generates short high pulses

💡 Explanation

Laser spiking occurs due to the gain medium's population inversion exceeding its limit because increased spontaneous emission creates relaxation oscillations which lead to output power fluctuations, therefore resulting in laser instability rather than stable emission.
