Abstract

We reported a high-power pure Kerr-lens mode-locked Yb:CALYO laser based on the dual-confocal cavity delivering sub-100-fs pulses. The output pulses at 81 MHz have an average power of 10.4 W and the pulse duration of 98 fs, corresponding to the peak power of 1.14 MW. This is, to the best of our knowledge, the highest average power ever reported for a Kerr-lens mode-locked Yb-bulk oscillator. Analysis of the dual-confocal cavity was also conducted, which indicates a way to achieve higher average power. We believe the result described in this Letter may pave a way to develop Kerr-lens mode-locked bulk lasers with much higher average power.

摘要

我们报道了一种基于双共焦腔的高功率纯克尔透镜锁模Yb:CALYO激光器，其输出亚100飞秒脉冲。81MHz重复频率下的输出脉冲平均功率为10.4W，脉冲持续时间为98飞秒，对应峰值功率为1.14MW。据我们所知，这是克尔透镜锁模Yb块状振荡器所报道的最高平均功率。我们还对双共焦腔进行了分析，这为实现更高平均功率指明了方向。我们相信本文所述结果可能为开发具有更高平均功率的克尔透镜锁模块状激光器铺平道路。
