光纤激光器仿真，包括端泵与侧面多点泵浦,适用于如镱离子等四能级系统,内含5个程序-simulation for fiber laser,including end pumping and multi-dot pumping

通过数值分析得到每段光纤的抽运光和激光衍双包层的分布，再通过坐标反变换对应到该段在整个光纤的位置(Through numerical analysis, the distributions of pumping light and laser diffraction double cladding are obtained, and then the position of the segment in the whole fiber
