在准连续情况下，通过求解低双折射光纤中含有拉曼效应的右旋与左旋圆偏振光所满足的耦合非线性薛定谔方程，着重研究了低输入功率和高输入功率情形在加入拉曼效应前后，有效偏振拍长和输入功率的变化关系。结果表明：无论入射光的偏振是沿着慢轴或沿着快轴，拉曼效应均改变了入射光偏振态演变的周期，同时改变了入射光的传输距离。

In low birefringence fiber, by solving the coupled nonlinear Schrodinger equations contained the Ra-man effect for satisfy right-and left-handed circularly polarized light in the quasi-CW case, the relationship be-tween the effective polarization beat length and changes of input power have been studied emphatically in low-and high input power situation considering the Raman effect or not.The results showed that the polarization state evo-lution cycles of the incident light can be changed and meanwhile the transmission distance of the incident light al-so can be changed due to Raman effect, regardless of the polarization of the incident light was along the slow axis or along the fast axis.
