← ScienceWhich outcome occurs when a pulsed laser's peak power exceeds the damage threshold of optical fiber?
A)Stimulated Brillouin scattering initiation✓
B)Improved signal-to-noise ratio
C)Enhanced fiber optic transmission
D)Increased Raman scattering efficiency
💡 Explanation
Stimulated Brillouin scattering will initiates because exceeding the power threshold causes phonon generation; this creates an acoustic wave that scatters the light backward, therefore reducing transmission rather than improving it; different mechanism than Raman scattering.
