← ScienceWhich consequence results when a pulsed laser ablates material?
A)Plasma forms above the surface✓
B)Surface becomes perfectly reflective
C)Material emits blackbody radiation
D)Laser induces nuclear fusion reactions
💡 Explanation
Plasma forms because the laser delivers energy rapidly; the mechanism is dielectric breakdown. This releases free electrons that collide with atoms. Therefore, superheated plasma is formed, rather than fusion, reflection changes, or just blackbody radiation.
