← ScienceWhich risk increases when a pulsed laser focused through a Kerr lens causes self-focusing?
A)Optical breakdown threshold decreases✓
B)Chromatic aberration becomes negligible
C)Group velocity dispersion is minimized
D)Spatial coherence of beam improves
💡 Explanation
The optical intensity from self-focusing exceeds the breakdown threshold because the Kerr effect causes a positive feedback loop, therefore, optical breakdown probability increases, rather than minimizing dispersion because pulse duration severely impacts laser output.
