We report on a passively mode-locked ytterbium-doped fiber laser with a repetition rate of 1.8 MHz. The laser was hybridly mode-locked via nonlinear polarization evolution and a semiconductor saturable absorber mirror. It generated chirped 3.8 ps long pulses with a pulse energy of 1.0 nJ which could be dechirped to a pulse duration of 93 fs.
我们报道了一台重复频率为1.8MHz的被动锁模掺镱光纤激光器。该激光器通过非线性偏振演化和半导体可饱和吸收镜实现混合锁模。它产生了啁啾的3.8ps长脉冲，脉冲能量为1.0nJ，可通过色散补偿将脉冲持续时间压缩至93fs。
