Abstract

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.
