| 摘 要： | 讨论了棱镜对的负色散效应,利用时域ABCD矩阵方法分析了高斯型光脉冲经棱镜对色散补偿系统的脉宽和啁啾的变化,指出输出光脉冲的脉宽是展宽还是压缩,与棱镜啁啾、棱镜间距和光脉冲在棱镜中传输的距离的取值有关.讨论了棱镜对色散补偿系统对脉冲压缩的最佳条件,指出此时输出光脉冲脉宽随棱镜啁啾的增大而骤减,且骤减程度随啁啾增大而逐渐削弱,最后趋于一稳定值.

| Abstract: | In this paper the negative dispersion of pairs of prisms was discussed. Then pulse width and chirp changes were analysed when it propagates through pairs of prisms. Widening or compressing the pulse width is related to the chirp of prisms, the distance between two prisms and the distance of the pulse propagating through pairs of prisms. The optimum compression condition is discussed for this system. The output pulse width decreased quickly when the chirp of prisms increased, then the decreasing speed turned slow. Finally, it is to a nearly invariable value. |
