A passively mode-locked Tm:CLNGG laser using single-walled carbon nanotubes (SWCNT) as a saturable absorber (SA) is demonstrated at 2017 nm. Pulses as short as 78 fs are generated at an 86 MHz repetition rate with an average output power of 54 mW. By increasing the output coupling from 0.5% to 1.5%, a higher power of 100 mW is achieved for slightly longer pulses with a duration of 105 fs at 1996 nm.
我们展示了一种基于单壁碳纳米管（SWCNT）作为可饱和吸收体（SA）的被动锁模 Tm:CLNGG 激光器，其工作波长为 2017nm。在 86MHz 的重复率下，我们获得了最短为 78fs 的脉冲，平均输出功率为 54mW。通过将输出耦合从 0.5%提高到 1.5%，我们在 1996nm 处获得了 100mW 的更高功率，同时脉冲持续时间略有增加到 105fs。
