Mode-locked laser operation near 2.05 µm based on a mixed sesquioxide : ceramic is demonstrated. Continuous-wave and wavelength-tunable operation is also investigated. Employing a GaSb-based semiconductor saturable absorber mirror as a saturable absorber, a maximum average output power of 133 mW is obtained for a pulse duration of 59 fs. Pulses as short as 54 fs, i.e., eight optical cycles are generated at a repetition rate of ∼78 with an average output power of 51 mW. To the best of our knowledge, this result represents the shortest pulse duration ever achieved from Tm-based solid-state mode-locked lasers.
展示了基于混合倍半氧化物陶瓷在2.05μm附近的锁模激光运行。还研究了连续波和波长可调谐运行。采用基于GaSb的半导体可饱和吸收镜作为可饱和吸收体，在脉冲持续时间为59 fs时获得了133 mW的最大平均输出功率。在重复频率约为78时产生了短至54 fs（即八个光学周期）的脉冲，平均输出功率为51 mW。据我们所知，该结果代表了基于Tm的固态锁模激光器所实现的最短脉冲持续时间。
