We realized a stable Kerr-lens mode-locked operation in a diode-pumped Yb:Y₃Ga₅O₁₂ laser. Pulses as short as 88 fs at the center wavelength of 1042 nm were obtained at a repetition rate of 159.3 MHz. The maximum output power was 104 mW under the incident pump power of 3.9 W. By comparing the mode-locked characteristics under different output transmissions, we obtained pulses with the highest output power of 330 mW and a duration of 149 fs. To the best of our knowledge, this is the first demonstration of a Kerr-lens mode-locked Yb:Y₃Ga₅O₁₂ laser.
我们在二极管泵浦的Yb:Y₃Ga₅O₁₂激光器中实现了稳定的克尔透镜锁模运转。在重复频率为159.3 MHz时，获得了中心波长为1042 nm、脉宽短至88 fs的脉冲。在3.9 W的入射泵浦功率下，最大输出功率为104 mW。通过比较不同输出透过率下的锁模特性，我们获得了输出功率最高为330 mW、脉宽为149 fs的脉冲。据我们所知，这是克尔透镜锁模Yb:Y₃Ga₅O₁₂激光器的首次演示。
