In this article we present a directly diode-pumped high-power Kerr-lens mode-locked Yb:CALGO bulk laser oscillator operating at 1-GHz repetition rate. We report on two laser configurations optimized for either highest average power or shortest pulse

Powerful Sub-100-fs Diode-Pumped Solid-State Laser Oscillator Operating at Gigahertz Repetition Rate

Conference on Lasers and Electro-Optics.
Our Kerr-lens mode-locked Yb:CALGO laser oscillator generates 93-fs pulses in 6.9-W and 48-fs pulses in 4.1-W at 1-GHz repetition rate. These are the shortest pulse duration and highest average power of any GHz-class Yb-based oscillator.

Thanks to their excellent thermal and spectral properties [1] and the possibility to pump them by high-power diodes, Yb-doped gain materials have revolutionized many application areas in ultrafast science [2] . However, laser oscillators based on tho

High-resolution spectroscopy in the mid-infrared requires stable frequency references. A frequency comb emitted by a quantum cascade laser is locked to a molecular transition, demonstrating 30-kHz frequency stability up to 5000-s integration time.

A novel pumping approach for Yb-doped gain materials enables a Kerr-lens mode-locked Yb-CALGO laser to overcome previous bandwidth limitations and to generate 22-fs pulses with an average power of 729 mW and 25% optical-to-optical efficiency.

We drive optical rectification in GaP directly inside a sub-100-fs Yb-oscillator at 22-W intracavity power and 7-W of pump power, leading to >10-fold increase of efficiency with respect to pump power compared to similar technologies.

So far, the operation of ultrafast bulk laser oscillators based on Yb-doped gain materials and directly emitting few-cycle pulses have been restricted to low optical-to-optical efficiencies and average output powers of only a few milliwatt. This perf
