Which consequence results when an optical isolator misaligns within fiber laser?

💡 Explanation

Misalignment causes increased back-reflections into the laser cavity; this triggers stimulated Brillouin scattering because back reflections interfere constructively, therefore SBS increases sharply rather than a gradual power decay or altered gain saturation.
