Which destructive consequence escalates when pulsed laser coherence increases?

A)Ablation threshold energy density decreases
B)Spectral broadening efficiency decreases
C)Material oxidation resistance increases
D)Nonlinear scattering cross-section diminishes

💡 Explanation

Increased laser coherence enables more efficient energy deposition, because constructive interference raises the peak intensity at a target site; therefore the ablation threshold decreases, rather than oxidation increasing which needs specific chemistry influences.
