We report on, to the best of our knowledge, the first sub-100 fs mode-locked Ho-laser in the 2 μm spectral range employing a disordered co-doped Tm,Ho:CaYAlO (Tm,Ho:CALYO) crystal as a gain medium. Pulses as short as 87 fs are produced with an average output power of 27 mW at 80.45 MHz repetition rate. An output power of 96 mW is reached for a pulse duration of 98 fs.
据我们所知，我们报道了在2μm光谱范围内首个采用无序共掺杂Tm,Ho:CaYAlO（Tm,Ho:CALYO）晶体作为增益介质的亚100 fs锁模Ho激光器。在80.45 MHz重复频率下产生了短至87 fs的脉冲，平均输出功率为27 mW。对于98 fs的脉冲持续时间，输出功率达到了96 mW。
