Which phenomenon results when a laser's temporal coherence degrades?

💡 Explanation

Degraded temporal coherence leads to lasers emitting a wider range of frequencies; this is because the interference fringes broaden, so the linewidth increases rather than cleaner monochromatic output, as high coherence yields, therefore the spectral bandwidth will increase rather than decrease.
