← ScienceWhich outcome occurs when a multi-kilowatt laser cutter’s beam experiences unintended power fluctuations during precision cutting?
A)Inconsistent material ablation rate✓
B)Harmonic frequency generation increases
C)Beam divergence sharply diminishes
D)Polarization becomes significantly more linear
💡 Explanation
Inconsistent material ablation occurs when the pulsed laser's intensity varies via the Photothermal effect, because variations drastically change the thermal energy deposited, therefore creating uneven cuts, rather than altering beam characteristics when power input changes.
