← ScienceWhich outcome results when a pulsed laser erodes a solid target?
A)Plasma formation and material ejection✓
B)Increased thermal conductivity of target
C)Crystalline phase transition of material
D)Enhanced optical transparency of the surface
💡 Explanation
Plasma ablated from the metal leads to material ejection due to a process called 'laser-induced breakdown spectroscopy'. This rapidly heats the material, leading to ionization and forming plasma, therefore causing ablation rather than increased conductivity, phase changes, or transparency under these high-energy conditions.
