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.
我们首次展示了飞秒锁模的 Tm，Ho 共掺晶体激光器在 2 微米光谱区运行。通过 Tm，Ho：KY（WO（4））（2）激光器产生了平均输出功率为 130mW 的 2055nm 的限幅 570fs 脉冲，脉冲重复频率为 118MHz。采用离子注入的 InGaAsSb 量子阱半导体可饱和吸收镜实现了锁模。
