Abstract
The threshold at which self-focusing initially dominates the dynamics of short-pulse propagation in normally dispersive bulk media, causing an explosive increase in peak intensity, is estimated analytically and verified numerically. Intensity-dependent propagation effects such as spectral broadening also occur explosively at this threshold.Keywords
