摘　　要：完整地将光脉冲的时间分量和空间分量耦合到一起 ,使得时间矩阵元素内有空间变量 ,空间矩阵元素中也有时间变量 。With the temporal components and spatial components combined in one matrix, the temporal elements can include spatial variables and the spatial elements can include temporal variables. The ray matrix which describes the spatial and temporal characteristics of femtosecond pulse in the Kerr medium was obtained. The results have been used for the analyses and calculations of self-mode-locked Ti: sapphire laser and Cr: LiSAF Kerr lens laser. The influence of the parameters of resonance cavity on the width of laser pulse was described, which can be used for the resonance cavity design.
