Canonical and Singular Propagation of Ultrashort Pulses in a Nonlinear Medium

Figure 4

Evolution of a pulse for large ( , (a)) and small ( , (b)) anomalous dispersion. In the latter case, there is compression both temporally and in the transverse direction. The bottom figure shows an incipient collapse event that will develop into a singularity with infinite amplitude.
