用分步法 计算 耦合非线性薛定谔方程

主要用于高功率锁模增益光纤激光器的数字模拟

模拟步骤 分四步： 光纤损耗传输 色散 非线性 增益

finding 是主程序，

其它是函数-Digital-to-analog simulation steps coupled nonlinear Schrö dinger equation is mainly used for high-power mode-locked gain fiber laser with a fractional step in four steps: the fiber loss transmission dispersion nonlinear gain finding is the main program, other functions
