| 摘 要： | 报道了一种基于非线性放大环镜和二硒化钼可饱和吸收体的混合锁模光纤激光器.该激光器采用双环形结构,以铥钬共掺光纤作为增益光纤.通过优化泵浦功率和偏振态,实验获得了调Q锁模脉冲、单脉冲、2～5多脉冲、脉冲束及脉冲束的2～4次谐波等5种输出状态.相比于单一锁模方式,混合锁模方式不但能使激光器实现自启动锁模,而且还能丰富其脉冲动力学状态.

| Abstract: | A hybrid mode-locked fiber laser based on nonlinear amplifying loop mirror and molybdenum diselenide saturable absorber is reported in this paper. By optimizing the pump power and polarization state, five types of different mode-locked states, such as Q-switched mode-locked pulse, basic mode-locked pulse, 2~5 multi-pulse, pulse beam, and 2~4 harmonic of pulse beam have been obtained in the experiment. Compared with the single mode-locked pattern, the hybrid mode locking pattern can not only realize the self-starting mode locking, but also enrich the pulse dynamic state. |
