非线性偏振旋转效应对主动锁模光纤激光器脉冲成形及稳定性的影响

Influence on Pulse Shaping and Stability of Nonlinear Polarization Rotation in an Actively Mode locked Fiber Laser

讨论了非线性偏振旋转效应对主动锁模光纤环形激光器脉冲成形及稳定性所起的作用。定性分析和实验结果均表明，适当控制腔内非线性偏振旋转，可形成一种特殊状态，在这种状态下，非线性偏振旋转效应同时起到压窄脉冲和改善稳定性的作用。

In this paper, the roles of nonlinear polarization rotation in an actively mode locked fiber ring laser were discussed. Both qualitative analysis and experimental results indicate that there is a special state at appropriate conditions in the ring cavity. In this state, both pulse compression and stability improvement can be achieved.
