← ScienceWhich consequence results when stimulated emission predominates in ruby laser?
A)Higher monochromaticity and beam coherence✓
B)Decreased energy conversion efficiencies
C)Increased spontaneous emission contribution
D)Reduced pumping intensity efficiency
💡 Explanation
Higher monochromaticity and coherence occurs because stimulated emission amplifies light with identical phase rather than incoherent spontaneous emission. Therefore, monochromaticity increases rather than observing wider spectral bandwidth because of greater coherence.
