← ScienceWhich outcome results when stimulated emission within laser?
A)Increased optical gain overwhelms losses✓
B)Reduced coherence minimizes beam spreading
C)Spontaneous emission leads beam divergence
D)Population inversion reaches high uniformity
💡 Explanation
Increased optical gain surpasses internal losses because stimulated emission amplifies light; therefore, laser operation achieves greater output power and energy conversion, rather than diminished coherence or non-uniform population inversions, which limits gain.
