Contribution
It introduces the highest peak power thin-disk oscillator to date, demonstrating a compact, stable design suitable for extreme ultraviolet applications.
Findings
Achieved 110 MW peak power
Produced 115 fs pulses at 14 MHz
Delivered 202 W average power
Abstract
A compact Kerr-lens mode-locked thin-disk oscillator delivering 110 MW output peak power, the highest among all oscillators, is reported. A pulse train with a repetition rate of 14 MHz carries 115 fs long, 14.4 uJ pulses resulting in 202 W of average power. This compact, simple, and stable oscillator is a suitable driver and an important milestone for further high harmonics generation and the development of extreme ultraviolet transportable frequency comb sources.
