Femtosecond mode locking of a Tm-doped Lu2O3 ceramic laser is reported. Transform-limited pulses as short as 180 fs are generated at 2076 nm with an average output power of 400 mW and a pulse repetition frequency of 121.2 MHz. An output power up to 750 mW can be reached at the somewhat longer pulse duration of 382 fs. Femtosecond pulse generation is realized in the 2030-2100 nm spectral range. Passive mode locking was achieved using an ion-implanted InGaAsSb quantum-well-based SESAM.
报道了掺铥的Lu2O3陶瓷激光器的飞秒锁模。在2076nm处产生了短至180fs的变换极限脉冲，平均输出功率为400mW，脉冲重复频率为121.2MHz。在382fs稍长的脉冲持续时间下，输出功率可达750mW。在2030 - 2100nm光谱范围内实现了飞秒脉冲产生。使用基于离子注入InGaAsSb量子阱的SESAM实现了被动锁模。
