The solution to the transfer equation for a femtosecond laser pulse with a length of several light oscillations in a linear dispersion medium is given. The transmission characteristics of the pulse are numerically simulated and the effects of normal and anomalous group velocity dispersion from electron and lattice on pulse broadening and pulse shape distortion are investigated respectively.
