In this paper, we demonstrate a 570.0 MHz harmonically mode-locked all-polarization-maintaining Ho-doped fiber laser based on semiconductor saturable absorbed mirror. Firstly, the laser operates in the 15.4 MHz fundamental mode-locked soliton regime, emitting 2051.5 nm, 1.62 ps soliton pulse without Kelly sidebands. And then, the stable 37th-order harmonic mode-locked soliton with maximum repetition rate up to 570.0 MHz at 2053nm is generated. Moreover, colorful soliton rain behaviors are also discussed.
在本文中，我们展示了一种基于半导体可饱和吸收镜的570.0兆赫兹谐波锁模全保偏掺钬光纤激光器。首先，该激光器工作在15.4兆赫兹的基模锁模孤子状态，发射波长为2051.5纳米、脉宽为1.62皮秒且无凯利边带的孤子脉冲。然后，在2053纳米处产生了最大重复频率高达570.0兆赫兹的稳定37阶谐波锁模孤子。此外，还讨论了彩色孤子雨现象。
