我们证明，第一次，我们的知识，飞秒制度模式锁定的Tm，Ho共掺杂晶体激光器工作在2微米光谱区域。Tm，Ho：KY（WO（4））（2）激光器在2055 nm处产生了570 fs的变换限制脉冲，该激光器在118 MHz的脉冲重复频率下产生了130 mW的平均输出功率。利用离子注入InGaAsSb量子阱半导体可饱和吸收镜实现了锁模。
We demonstrate, for the first time to our knowledge, femtosecond-regime mode locking of a Tm,Ho-codoped crystalline laser operating in the 2 microm spectral region. Transform-limited 570 fs pulses were generated at 2055 nm by a Tm,Ho:KY(WO(4))(2) laser that produced an average output power of 130 mW at a pulse repetition frequency of 118 MHz. Mode locking was achieved using an ion-implanted InGaAsSb quantum-well-based semiconductor saturable absorber mirror.
