← ScienceWhich risk increases when adaptive optics fail during laser micromachining?
A)Reduced kerf width precision
B)Elevated back reflection intensity
C)Increased material heat affected zone✓
D)Diminished plasma formation duration
💡 Explanation
Increased material heat affected zone results because without adaptive optics, precise focusing declines, diminishing ablation efficiency; therefore more laser energy is absorbed as heat, rather than vaporization, causing HAZ rather than precise cuts.
