Paper Abstract

The combined effect of diffraction, anomalous dispersion and nonlinear refraction under both symmetric and unsymmetric initial conditions is studied by using a variational approach and numerical simulation. It is shown that the compression parameter Bo which strongly depends on the initial condition and the nonlinear interplay strength, plays an important role. When Bo > 0, the beam width and pulse width blow up vibrantly as z yields (infinity) . When Bo < 0, the pulse collapses oscillatorily and simultaneously both in space and time.
