We report on a Kerr-lens mode-locked Yb:YSO lasers for the first time. Pumped by a single-mode fiber laser with high brightness and linear polarization, the Yb:YSO laser can deliver as high as 2 W average power with as short as 95 fs pulse duration at the repetition rate of 137.2 MHz, resulting in the single pulse energy of 14.8 nJ and the peak power of 155.7 kW. This work proves the potential on generation of sub-100 fs pulses with multi-watt level average power with the Yb doped oxyorthosilicates crystals.
我们首次报道了克尔透镜锁模Yb:YSO激光器。由具有高亮度和线性偏振的单模光纤激光器泵浦,Yb:YSO激光器在137.2 MHz的重复频率下,能够输出高达2 W的平均功率,脉冲持续时间短至95 fs,单脉冲能量为14.8 nJ,峰值功率为155.7 kW。这项工作证明了利用掺Yb的正硅酸氧盐晶体产生平均功率为多瓦级、脉冲持续时间低于100 fs的脉冲的潜力。
