← ScienceWhich consequence results when low temporal coherence fiber couples pulsed laser?
A)Pulse broadening due group velocity dispersion✓
B)Increased efficiency via stimulated raman effect
C)Reduced fiber damage by self-focusing
D)Improved signal-to-noise via shot noise reduction
💡 Explanation
Pulse broadening occurs when low coherence laser is used due to group velocity dispersion; because different frequencies travel at different speeds which cause temporal broadening, rather than higher efficiencies or reduced damage. Temporal coherence determines pulse duration spread.
