← ScienceWhich outcome occurs when a high-power laser exceeds the damage threshold of an optical isolator?
A)Stimulated Brillouin scattering increases✓
B)Kerr effect enhances self-focusing
C)Thermal lensing reduces beam quality
D)Two-photon absorption becomes dominant
💡 Explanation
Increased laser power can cause stimulated Brillouin scattering (SBS) because the intensity of the back-reflected light increases non-linearly above a threshold, therefore optical components fail due to excessive heat rather than other non-linear effects.
