据我们所知，我们首次报道了Tm，Ho:NaY(WO(4))(2)激光器在2060nm左右的飞秒脉冲操作。在144兆赫脉冲重复频率下，产生变压器限制的191秒脉冲，平均输出功率为82毫瓦。最大输出功率可达155兆瓦，相应的脉冲持续时间为258秒。采用离子注入的InGaAsSb量子阱型半导体可饱和吸收镜进行被动锁模维护。
We report, for the first time to our knowledge, femtosecond-pulse operation of a Tm,Ho:NaY(WO(4))(2) laser at around 2060 nm. Transform-limited 191 fs pulses are produced with an average output power of 82 mW at a 144 MHz pulse repetition frequency. Maximum output power of up to 155 mW is generated with a corresponding pulse duration of 258 fs. An ion-implanted InGaAsSb quantum-well-based semiconductor saturable absorber mirror is used for passive mode-locking maintenance.
