← ScienceWhich consequence results when laser-induced damage threshold is surpassed?
A)Material ablation begins on the target.✓
B)Coherent length increases dramatically.
C)Nonlinear refractive index stabilizes output.
D)Mode-locking initiates spontaneously inside cavity.
💡 Explanation
When the laser energy exceeds the LIDT, localized heating causes rapid phase change, therefore material ablation begins via thermal runaway, rather than other nonlinear optical effects, because ablation occurs under conditions exceeding the rated operating temperature.
