Which risk increases when a laser's coherence length degrades?

A)Speckle contrast in imaging increases
B)Pulse duration after compression decreases
C)Material ablation thresholds become lower
D)Chromatic dispersion effects are minimized

💡 Explanation

Speckle contrast increases because shorter coherence length means light from different parts of the sample interferes less predictably via constructive & destructive interference, therefore speckle contrast rises, rather than other listed outcomes that favor increased coherence.
