We report on the first sub-100 fs mode-locked laser operation of a Tm-doped disordered calcium lithium tantalum gallium garnet (Tm:CLTGG) crystal. Soliton mode-locking was initiated and stabilized by a transmission-type single-walled carbon nanotube saturable absorber. Pulses as short as 69 fs were achieved at a central wavelength of 2010.4 nm with an average power of 28 mW at a pulse repetition rate of ∼87.7 MHz. In the sub-100 fs regime, the maximum average output power amounted to 103 mW.
我们报道了掺铥无序钙锂钽镓石榴石（Tm:CLTGG）晶体首次实现亚100飞秒锁模激光运转。利用透射型单壁碳纳米管可饱和吸收体启动并稳定了孤子锁模。在中心波长2010.4 nm处获得了短至69飞秒的脉冲，脉冲重复频率约为87.7 MHz，平均功率为28 mW。在亚100飞秒范围内，最大平均输出功率达到103 mW。
