We report on a mode-locked Tm,Ho:CLNGG laser emitting in the 2 µm spectral range using single-walled carbon nanotubes (SWCNTs) as a saturable absorber (SA). Pulses with duration of 98 fs are generated at 99.28 MHz repetition rate with an average output power of 123 mW, yielding a pulse energy of 1.24 nJ. Using a 0.5% output coupling, pulses as short as 67 fs, i.e., 10 optical cycles, are produced after extracavity compression with a 3-mm-thick ZnS plate.
我们报道了一种锁模Tm,Ho:CLNGG激光器，它使用单壁碳纳米管（SWCNT）作为可饱和吸收体（SA），在2 µm光谱范围内发射。在99.28 MHz重复频率下产生了持续时间为98 fs的脉冲，平均输出功率为123 mW，脉冲能量为1.24 nJ。使用0.5%的输出耦合，在通过一块3毫米厚的ZnS板进行腔外压缩后，产生了短至67 fs（即10个光学周期）的脉冲。
