Which risk increases when optical gain suddenly drops in a pulsed laser?

A)Spontaneous emission dominates amplified signal✓

B)Mode locking becomes self-sustaining

C)Q-switching becomes more reliable

D)Higher pulse repetition frequencies achievable

💡 Explanation

Spontaneous emission overwhelms the rapidly diminishing stimulated emission, because population inversion collapses quickly due to insufficient optical gain promoting stimulated emission; therefore the amplified signal is swamped, rather than improved mode locking or better Q-switching occurring.
