【Abstract】 This paper studies the propagation of ultrashort laser pulse in the dispersion of the optical fiber,and changes the temporal region into the spectrum region by the Fourier transformation technique.As the pulse is Gaussian pulse,the theoretic formula of the variation of ultrashort pulse with the time and the propagation distance is given,and the influence of the different disperse order on the pulse profile is also discussed.The results show that the second dispersion order spreads the pulse and the third dispersion order deforms the pulse.更多还原
