← ScienceWhich outcome results when a pulsed laser drills materials?
A)Material ablation through rapid vaporization✓
B)Recrystallization via slow thermal diffusion
C)Plasma shielding inhibits deep penetration
D)Heat conduction causes uniform melting
💡 Explanation
Material ablation occurs because intense laser pulses cause rapid phase change and localized heating for vaporization faster than heat dissipates, therefore direct material removal rather than just melting occurs because heat-affected zones are minimized.
