← ScienceWhich consequence results when attempting to drill a hole through a diamond using very short pulses from a high-powered femtosecond laser?
A)Increased heat-affected zone and cracking
B)Precise material ablation with minimal melting✓
C)Significant changes to diamond's crystal structure
D)Rapid oxidation of the diamond surface
💡 Explanation
Precise material ablation occurs because the ultrashort pulsed laser induces multi-photon ionization, causing direct transition to plasma and rapid material removal rather than significant heat diffusion. Therefore, material is cleanly ablated, rather than causing cracking.
