A high-power (>1 W) pure Kerr-lens mode-locked bulk Yb:KGW laser with multimode fiber-coupled diode pumping was demonstrated. The laser delivered 240 fs pulses with 2.3 W of average output power at 86.8 MHz, corresponding to 97 kW of peak power and 26 nJ of pulse energy. The shortest generated pulse duration was 120 fs with 1.2 W of output power. The self-starting regime was also observed with a background continuous-wave component. The laser exhibited more than an order of magnitude higher output power when compared to the previously reported bulk Yb-ion-doped lasers with multimode laser diode pumping systems.
展示了一种采用多模光纤耦合二极管泵浦的高功率（>1 W）纯克尔透镜锁模块状Yb:KGW激光器。该激光器输出240 fs脉冲，平均输出功率为2.3 W，重复频率为86.8 MHz，对应峰值功率97 kW，脉冲能量26 nJ。产生的最短脉冲持续时间为120 fs，输出功率为1.2 W。还观察到了具有背景连续波分量的自启动状态。与先前报道的采用多模激光二极管泵浦系统的块状Yb离子掺杂激光器相比，该激光器的输出功率高出一个数量级以上。
