Which consequence results when the coherence length decreases in a pulsed laser being used for LIDAR?

A)Reduced range and accuracy
B)Increased signal-to-noise ratio
C)Lower power supply requirements
D)Enhanced material ablation rates

💡 Explanation

Decreased laser coherence length broadens the pulse's bandwidth, reducing interference efficiency in LIDAR, because the *temporal coherence* degrades. Therefore, range decreases, and accuracy degrades, rather than improving ablation or conserving power because these are consequences of other factors like pulse duration.
