Abstract
Recent work has shown that the fully spatio-temporal propagation of a light wave envelope in a cubically nonlinear medium displays, in addition to the usual transverse structures, longitudinal dynamics which play an essential role in the evolution of the wave [1, 2, 3]. A recent computational effort has illustrated that the presence of dispersion can inhibit collapse due to two dimensional self focusing in normally dispersive media causing structure in the propagation direction as well as the transverse direction [3]. Analysis of three dimensional propagation of light waves in anomalously dispersive media [4, 5] reveals a set of symmetric solutions which would exist in the intermediate state between collapse and dispersal.
