报道了在非线性放大环镜锁模的8字形光纤激光器中，高次谐波孤子分子与类矩形噪声脉冲（NLP）共存的现象。谐波孤子分子具有936.6MHz的重复频率，对应于基本腔重复频率的466次谐波，孤子间隔为16.5ps。同时，矩形NLP以基本重复率操作。此外，这两种类型的脉冲可以通过操纵偏振控制器独立地产生。实验结果证明了光纤激光器有趣的工作机制，有助于丰富光纤激光器锁模脉冲的动力学特性。(C)2016美国光学学会
We report the coexistence of high-order harmonic soliton molecules and rectangular noise-like pulses (NLP) in a figure-eight fiber laser mode-locked by a nonlinear amplifying loop mirror. The harmonic soliton molecule has a repetition rate of 936.6 MHz, corresponding to the 466th harmonics of the fundamental cavity repetition rate, with soliton separation of 16.5 ps. Meanwhile, the rectangular NLP operates at the fundamental repetition rate. In addition, these two types of pulses could be generated independently by manipulating the polarization controllers. The experimental results demonstrate an interesting operation regime of the fiber laser and contribute to enriching the dynamics of mode-locked pulses in fiber lasers.
