← ScienceWhich risk increases when a pulsed laser ablates material?
A)Plasma absorption shifts pulse duration✓
B)Material reflectivity impedes beam focus
C)Chromatic dispersion limits pulse compression
D)Stimulated emission ends target penetration
💡 Explanation
As power density rises beyond plasma formation threshold, inverse Bremsstrahlung causes dominant plasma absorption; therefore less laser energy ablates, rather than reflection dominating or self-terminating, because lower energy is delivered.
