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 is obtained by Inverse Coordin
