Which consequence results when self-focusing occurs in pulsed lasers?

💡 Explanation

Spatial beam collapse occurs because changes in optical medium refractive index result in positive feedback from accumulated nonlinearities; eventually, this becomes self-focusing, leading to thermal damage rather than stable emissions, therefore collapsing the beam profile.
