Based on the generalized nonlinear Schrdinger equation, the propagation characteristics of a super Gaussian femtosecond pulse in photonic crystal fibers were numerically simulated by split-step Fourier method. The result shows that soliton disintegration occured in shorter distances and soliton self-frequency shift was more remarkable for super Gaussian pulse than for Gaussian pulse, and a new lower power soliton appeared on the left side of the strong soliton. Otherwise, the 3rd-dispersion would lead to the dissymmetry and the complex structure for the pulse shape and its spectrum, and that would lead to the trend to form soliton. The pulse shape was smoothed by intrapulse stimulated Raman scattering. At the same time the energy between the two solitons was redistributed by self-ste
