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 B_o which strongly depends on the initial condition and the nonlinear interplay strength, plays an important role. When B_o > 0, the beam width and pulse width blow up vibrantly as z yields (infinity) . When B_o < 0, the pulse collapses oscillatorily and simultaneously both in space and time.
