摘　　要：利用空间－时间类似和光线光学方法得到啁啾高斯光脉冲在类时间透镜介质中传播的解析解，讨论了光脉冲宽度和啁啾参数随传播距离的演变，并与光脉冲在克尔介质中传播的特征作了比较。Using the similarity between the time and space and adopting the ray trace method, the analytical solutions to the equation of the propagation of chirped pulses inside the temporal lenslike media have been deduced. With the aid of the solutions, the periodic variation features of the chirped pulses traveling inside the temporal lenslike media have been specified, especially evolution of the pulse width and chirp parameter with the propagation distance analyzed. Also, comparisons have been made between the soliton like waves traveling inside the temporal lenslike media and the solitons propagating inside the Kerr media.
