Abstract

We report on the generation of 67 fs pulses from a diode pumped Kerr-lens mode-locked Yb:KGW bulk laser. The average output power reached 3 W, corresponding to >38 nJ of pulse energy and >570 kW of peak power. The mode locking was initiated by a semiconductor saturable absorber. To the best of our knowledge, this is the highest average output power produced to date from Yb-ion based bulk lasers with such a short pulse duration.

摘要

我们报道了从二极管泵浦的克尔透镜锁模Yb:KGW体激光器产生67飞秒脉冲的情况。平均输出功率达到3瓦，对应脉冲能量大于38纳焦，峰值功率大于570千瓦。锁模由半导体可饱和吸收体启动。据我们所知，这是迄今为止基于Yb离子的体激光器在如此短的脉冲持续时间下产生的最高平均输出功率。
