We demonstrate a fundamentally mode-locked Yb-fiber laser with 3 GHz repetition rate and ∼206 fs pulse duration. The laser incorporates two enabling technologies: a 1 cm heavily Yb-doped phosphate glass fiber as the gain medium and a high-dispersion (-1300 fs2) output coupler to manage cavity dispersion. The oscillator self-starts and generates up to 53 mW average power.
我们展示了一种具有 3GHz 重复率和约 206fs 脉冲持续时间的基本锁模 Yb 光纤激光器。该激光采用了两种实现技术:1cm 长的高浓度 Yb 掺杂磷酸盐玻璃光纤作为增益介质和具有高色散(-1300fs2)的输出耦合器来管理腔色散。振荡器自启动并产生高达 53mW 的平均功率。
