Which outcome occurs when injecting a high-power laser beam into a normally transparent silica fiber optic cable?

💡 Explanation

Stimulated Brillouin scattering causes significant backscattering because the high optical intensity initiates acoustic phonons, therefore producing a reflected wave interfering with the forward beam, rather than simple absorption.
