报道了一种工作在类孤子区的高脉冲能量被动锁模光纤激光器。该激光器基于线性腔设计。采用一段掺Yb单偏振大模场面积光子晶体光纤作为增益介质，利用高对比度半导体可饱和吸收镜实现自启动锁模。该激光器直接产生600 fs脉冲，平均功率为900 mW，重复频率为47.3 MHz，对应于19 nJ的单脉冲能量。此外，该光纤激光器直接用于泵浦ZnTe产生宽带太赫兹辐射，导致紧凑的太赫兹源。
A high pulse energy passively mode-locking fiber laser operating in the soliton-like regime is demonstrated. The laser is based on a linear cavity design. A segment of Yb-doped single-polarization large-mode-area photonic crystal fiber serves as the gain medium, and the self-starting mode-locking is achieved by a high contrast semiconductor saturable absorber mirror. The laser directly generates 600-fs pulses with 900 mW of average power at a repetition rate of 47.3 MHz, corresponding to a single pulse energy of 19 nJ. Furthermore, this fiber laser is directly used for pumping ZnTe to generate broadband terahertz radiation, resulting in a compact terahertz source.
