Which mechanism limits the energy focusing of pulsed lasers?

💡 Explanation

Self-focusing arises because the intensity-dependent refractive index creates a lens effect, leading to collapse. The focus spot cannot be confined indefinitely within some mediums therefore catastrophic damage, rather than tighter focusing, occurs at high powers.
