受激拉曼散射对被动锁模光纤环形孤子激光器的影响

The Effects of Stimulated Raman Scattering on Passive Mode locked Fiber Ring Soliton Laser

用守恒量扰动法详细分析了拉曼散射对非线性偏振旋转光纤环形孤子激光器的稳定性及脉宽的影响，通过孤子参量演化方程的求解，获得激光器稳定运行之后孤子脉宽的解析表达式以及激光器的稳定运行条件。

In this paper, we analyse the effects of stimulated Raman scattering on the stable condition and soliton width of the fiber ring soliton laser locked by nonlinear polarization rotation. By solving the evolution equations, the stable condition and analytic expressions for soliton width of the passive mode locked fiber ring soliton laser are obtained.
