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.
我们首次报告了 Tm,Ho:NaY(WO(4))(2) 激光在 2060nm 附近的飞秒脉冲操作。在 144MHz 脉冲重复频率下，获得了限宽为 191fs 的脉冲，平均输出功率为 82mW。当采用相应的 258fs 脉冲持续时间时，获得了高达 155mW 的最大输出功率。使用基于离子注入的 InGaAsSb 量子阱半导体可饱和吸收镜来维持被动锁模。
