自锁模激光器时-空矩阵q-p参数分析方法的研究

Analysis Method of q p Parameter in Spatial temporal Matrix in Self mode locked Lasers

利用时－空矩阵ｑ－ｐ 参数分析方法讨论了相干光脉冲在自锁模激光谐振腔中的传输特性。通过数值计算模拟了掺钛蓝宝石飞秒激光器谐振腔中光斑和脉冲宽度在自锁模过程中的演变。计算过程简明，直观，与实验结果较好吻合。

We have developed a Analysis method of Q P parameter in spatial temporal matrix in self mode locked lasers.The evolution of beam size and pulse duration in a cavity of Ti:sapphire femtosecond laser is presented by means of simulated calculation.The method is simply and clear,and the theoretical results are in accordance with experimental one.
