Which outcome occurs when a pulse-compressed laser emits towards a Kerr-effect-based nonlinear crystal?

💡 Explanation

Self-focusing intensifies because the optical Kerr effect induces a refractive index change that focuses the beam as intensity increases. This causes increased self-focusing, rather than broadening, because photons are focused therefore spatial coherence wouldn't directly lessen.
