阐述了光纤拉曼放大器的原理、分类，并对其研究现状、发展趋势和研究展望进行了探讨和总结。其中，采用有限元法，着重数值仿真了光纤拉曼放大器放大信号的原理过程。结果表明，基于Chraplyvy模型能够较好地模拟出受激拉曼散射作为光纤拉曼放大器原理的过程，并且其程序运行效率高于采用洛仑兹模型。通过研究综述，为光纤拉曼放大器的理论研究、实验和工程应用测试工作提供了参考。

At first ,the fibre Raman amplifier(FRA)’s principle ,classification and characteristics are described .Then ,the main research direction and its development are analyzed .The key point is numeric simulation of FRA ’s amplification of signal by the finite element meth-od .It is found that stimulated Raman scattering (SRS ) which is the principle of FRA can be better numerically simulated by Chraplyvy model than Lorentz model in program efficiency .The conclusions are helpful to the study of fibre Raman amplifier .
