The performance of multiwavelength Yb-doped double-clad fiber lasers is analyzed based on a FabryPerot flter, and the wavelength dependence of reflectivity of dichroic mirror in the filter has been taken into account. It is found that the reflectivity of DCF facets and dirchroic mirror can obviously influence the performance, and there is an optimal value of the reflectivity of DCF facets.
从理论上分析了由F-P滤波器实现的多波长双包层光纤激光器的边界条件和输出功率，在考虑了F-P滤波器中双色镜反射率的波长依赖关系的前提下，对影响多波长输出功率和消光比的参数如双色镜和光纤出光端面的反射率、抽运功率等进行了研究。
