← ScienceWhich consequence results when stimulated Raman scattering is unsuppressed in high-powered fiber lasers?
A)Reduced amplifier gain efficiency✓
B)Reduced heat dissipation requirements
C)Increased spectral beam confinement
D)Increased laser diode longevity
💡 Explanation
Amplifier gain efficiency decreases with unsuppressed stimulated Raman scattering in fiber lasers because optical power transfers to longer, less amplified wavelengths. Therefore usable amplified power diminishes, rather than maintaining efficient signal amplification because the gain medium depletes.
