摘　　要：本文分析了双折射双频激光器增益曲线的特点，增益曲线影响频率稳定性，比较了不同比例的Ｎｅ^（２０）和Ｎｅ^（２２）形成的增益曲线，通过分析和实验获得最佳的Ｎｅ^（２０）和Ｎｅ^（２２）的比例，实验结果改善了频率稳定度。The birefringent double freqUency laser is a newly developed laser,its difference of frequencies is wider than convention double frequency laser,up to hundreds mophertz.It is important toselect proper frequency stabilization methonology, and the frequency stabilization methods suffer fromthe effecting of the gain curve properties.In this paper,the analysis on the characteristics of gain curveof a inside birefringent double frequency He-Ne laser is presented. Selecting the ratio Ne20: Ne22 canchange the gain curve.In terms of the experiments and calculating,the optimum ratio of Ne20: Ne22 is53:47,and the gain curve has beter symmetry,the peak point of the curve can be selected to be the frequency control operation point.
