本文报道了由纯正常色散光纤制成的被动锁模光纤环形激光器的工作情况。利用非线性偏振旋转技术仍能实现激光器的自启动锁模，锁模脉冲具有脉冲能量大、频率啁啾强、锁模谱宽受激光器有效增益带宽限制等特点。此外，我们表明，该激光器的操作可以很好地描述了一个扩展的Ginzburg-Landau方程模型，管理光纤激光器的孤子动力学。
We report on the operation of a passively mode-locked fiber ring laser made of purely normal dispersive fibers. Self-started mode locking can still be achieved in the laser by use of the nonlinear polarization rotation technique, and the mode-locked pulse has large pulse energy, strong frequency chirp, and a mode-locked spectral width limited by the effective laser gain bandwidth. Furthermore, we show that the operation of the laser can be well described by an extended Ginzburg-Landau equation model that governs the soliton dynamics of fiber lasers.
