← ScienceWhich outcome occurs when stimulated emission dominates in an optical gain medium?
A)Amplified coherent light beam emerges✓
B)Electromagnetic radiation is immediately absorbed
C)Spontaneous decay probability is reduced
D)Gain of photons is temporarily suppressed
💡 Explanation
Amplified coherent light beam emerges because stimulated emission causes photons in-phase with the incident photon to be emitted, therefore coherent amplification occurs rather than incoherent spontaneous emission or absorption under non-lasing conditions.
