摘要
Based on the constant coefficients of Ginzburg-Landau equation that considers the influence of the doped fiber retarded time on the evolution of self-similar pulse,the parabolic asymptotic self-similar solutions were obtained by the symmetry reduc-tion algorithm. The parabolic asymptotic amplitude function,phase function,strict linear chirp function and the effective temporal pulse width of self-similar pulse are given in this paper. And these theoretical results are consistent with the numerical simulations.
