摘要

采用分步傅里叶方法建立了高功率连续掺镱光纤激光器的数值模型。受激拉曼散射(SRS)通过众所周知的硅纤维拉曼传递函数被纳入模型。为了减小SRS对激光发射光谱含量的影响，改变了增益光纤和光纤布拉格光栅的参数。

Numerical investigation of the Raman instability in high-power CW ytterbium-doped fiber lasers

A numerical model of a high power CW ytterbium-doped fiber laser has been developed using the split-step Fourier method. Stimulated Raman scattering (SRS) is included in the model via the well-known Raman transfer function of silica fibers. The parameters of the gain fiber and of the fiber Bragg gratings are varied in order to minimize the impact of SRS on the spectral content of laser emission.
