分析了一种新型的主被动锁模光纤环形孤子激光器．通过路径平均非线性薛定谔方程的求解．获得了激光器稳定运行的条件，并作了数值模拟，得到了工作波长为１．５５μｍ时．脉宽为９８５ｆｓ．谱宽为３２３ＧＨｚ．重复频率为１０ＧＨｚ的双曲正割变换限制孤子脉冲序列。
A new type of active mode-locked fiber ring soliton laser is analyzed. Solution of the Mean Nonlinear Schr? Dinger Equation Through the Paths. The conditions for the stable operation of the laser were obtained, and the numerical simulation was done. The working wavelength was 1.55μm. The pulse width is 985fs. The spectral width is 323GHz. Hyperbolic secant transformation with a repetition rate of 10 GHz limits the soliton pulse sequence.
