← ScienceWhich consequence results when power increases in a laser-cutting system?
A)Plasma formation shields base metal✓
B)Decreased material thermal stress occurs
C)Reflected beam power couples back
D)Photon bunching enhances cutting quality
💡 Explanation
Plasma formation occurs because increased laser power causes rapid ionization of the vaporized material via inverse Bremsstrahlung. This shields the underlying material, therefore reducing cutting efficiency, rather than aiding in the cutting process.
