THEORY OF MODE LOCKING WITH A NONLINEAR MIRROR

对于均匀展宽激光器的非线性镜锁模，提出了一种解析分析方法。所得脉冲包络为时间的双曲正割函数。得到了脉冲宽度的简单解析表示，并对结果进行了讨论。

This paper presents a closed form analysis method of nonlinear mirror mode lo-cking of a homogeneously broadened Laser.The pulse envelope we obtained is a hy-perbolic secant function of time. We obtain the simple analytic expression for the pu-lse length and discuss the results.
