← ScienceWhich consequence results when excessive optical feedback corrupts a pulsed laser?
A)Increased multi-mode lasing threshold
B)Reduced pulse energy fluctuations
C)Mode-locking phase disturbances manifest✓
D)Gain medium bleaching saturation accelerates
💡 Explanation
Disturbances in timing jitter occur because excessive feedback causes mode competition, leading to mode-locking phase disturbances. Therefore, accurate synchronization is lost rather than improvements in pulse energy because unwanted reflections interfere with stable pulse formation.
