We report a 10 GHz harmonically and regeneratively mode-locked Yb fiber laser with a phase-locked loop (PLL) technique at 1.1 μm. Stable mode locking was achieved by optimizing the average dispersion of the fiber cavity to an anomalous dispersion to operate as a soliton laser. As a result, a 1.1 ps optical pulse with a timing jitter of 140 fs was successfully generated.
我们报道了一种采用锁相环（PLL）技术、工作波长为1.1μm的10GHz谐波锁模和再生锁模掺镱光纤激光器。通过将光纤腔的平均色散优化为反常色散以使其作为孤子激光器工作，实现了稳定锁模。结果，成功产生了脉宽为1.1ps、定时抖动为140fs的光脉冲。
