In this paper, the carrier‐envelope‐offset (CEO) frequency stabilization of a Kerr‐lens mode‐locked femtosecond oscillator with average power 105 W is presented. Intra‐cavity Kerr lensing is realized in a quartz crystal that simultaneously serves as an acousto‐optic loss modulator. This novel method results in a CEO frequency stable laser with high average power and a residual in‐loop phase noise below 90 mrad. Furthermore, an all‐solid‐state bulk broadening stage is presented. The compressed, CEO frequency‐stabilized output has a peak power exceeding 67 MW at a pulse duration of 40 fs and a repetition rate of 15.6 MHz. The intra‐cavity peak power of the CEO frequency‐stabilized oscillator is around 200 MW. These results pave the way toward compact, transportable all‐solid‐state drivers with high repetition rates for deep UV and XUV frequency combs and other nonlinear processes.

载波包络偏移频率稳定100 W级飞秒薄盘振荡器

本文介绍了平均功率为105 W的Kerr-lens锁模飞秒振荡器的载波包络偏移（CEO）频率稳定度。腔内Kerr透镜由石英晶体实现，同时用作声光损耗调制器。这种新颖的方法可产生具有高平均功率和低于90 mrad的残留环路内相位噪声的CEO频率稳定激光器。此外，还介绍了一个全固态的散装扩展阶段。经压缩的CEO频率稳定输出在40 fs的脉冲持续时间和15.6 MHz的重复频率下具有超过67 MW的峰值功率。CEO频率稳定振荡器的腔内峰值功率约为200 MW。这些结果为紧凑化铺平了道路，
