We demonstrate the passive mode-locking operation of an in-band-pumped Ho:YLiF(4) laser at 2.06 μm using a semiconductor saturable absorber mirror based on InGaAsSb quantum wells. A transform-limited pulse train with minimum duration of 1.1 ps and average power of 0.58 W has been obtained at a repetition frequency of 122 MHz. A maximum output power of 1.7 W has been generated with a corresponding pulse duration of 1.9 ps.
我们使用基于 InGaAsSb 量子阱的半导体可饱和吸收镜演示了在带内泵浦 Ho:YLiF(4) 激光的被动锁模运转，得到了重复频率为 122 MHz、最短脉冲持续时间为 1.1 ps、平均功率为 0.58 W 的变换极限脉冲串。在相应的 1.9 ps 脉冲持续时间下，获得了 1.7 W 的最大输出功率。
