| Abstract: | The solution of propagation equation of femtosecond laser pulse with duration of several optical oscillation periods is presented without consideration of group velocity dispersion.By simulating numerically the nonlinear propagation of femtosecond laser pulse,we investigated the influence of nonlinear effect on pulse shape and spectrum.The result we got does not coincide exactly with that of slowly varying envelope approximation. |

| Keywords: | femtosecond laser pulse dispersion free propagation nonlinear effect quartz medium |
