← ScienceWhich consequence results when excessive power reflects back into a CW laser?
A)Increased junction temperature in diode✓
B)Stimulated Brillouin scattering increases linearly
C)Reduced mode-locking pulse duration
D)Higher Q cavity, reduced bandwidth
💡 Explanation
Laser diodes are susceptible to damage from back reflections; therefore, the increased power deposition leads to an increase in junction temperature because of thermal runaway due to decreased resistance, rather than a beneficial operating characteristic.
