← ScienceWhich outcome occurs when a pulsed laser deposits energy rapidly into a solid?
A)Ablative material removal begins rapidly✓
B)Refractive index variation decreases smoothly
C)Coherent phonon generation occurs chaotically
D)Thermal conductivity stays precisely constant
💡 Explanation
Ablative material removal occurs because the intense energy causes rapid vaporization via the mechanism of photothermal ablation; therefore, material is ejected, rather than a smooth change in refractive index or the coherent phonon generation because the material is immediately ejected.
