← ScienceWhich outcome occurs when a pulsed laser ablates a metallic target in reactive atmosphere?
A)Plasma-assisted chemical reaction occurs✓
B)Increased specular reflection of surface
C)Enhanced thermal conductivity occurs
D)Material phase transition is suppressed
💡 Explanation
Plasma-assisted chemical reaction occurs because high-energy laser pulses generate plasma igniting chemical processes, therefore new compounds are formed, rather than simple heating dominating due to rapid ionization timescales.
