| 摘 要： | 为了对多点抽运的高功率双包层光纤激光器进行深入的理论分析,从掺Yb双包层光纤激光器的速率方程和边界条件出发,对多点抽运的双包层光纤激光器的数值分析方法进行了研究。通过坐标比例变换和抽运光与激光的连续性边界条件变换,将多点抽运的高功率双包层光纤激光器的数值分析模型转化为两点边值问题,然后利用两点边值问题的数值分析方法有效地进行求解,得到了抽运光和激光沿双包层光纤的分布。通过对多点抽运的双包层光纤激光器进行数值分析,不仅得到了激光器的输出功率,还能够得到抽运光损耗以及激光损耗数值大小等数据,有助于多点抽运的双包层光纤激光器的优化分析和设计。结果表明,该数值分析方法对多点抽运的双包层光纤激光器的深入研究非常有意义。

| Abstract: | In order to theoretically study high-power multi-position-pumped double-clad fiber lasers intensively,the numerical analysis methods for this kind of fiber lasers were studied,based on the rate equations and boundary conditions of Yb-doped double-clad fiber lasers.By coordinate scale transform and continuum boundary transform of pumping powers and laser powers,the multi-position-pumped double-clad fiber lasers were transformed into two-boundary value problems and could be numerically analyzed effectively.And the power distributions of pumping lights and lasers along the double-clad fiber laser could be obtained.With numerical analysis,output powers,lost pumping powers and lost laser powers of the multi-position-pumped double-clad fiber lasers could be obtained also,which is very helpful for the optimal analysis and design of this kind of fiber lasers.The research shows that the numerical analysis methods are valuable for advanced study of multi-position-pumped double-clad fiber lasers. |
