100 MW Thin-Disk Oscillator

Deep UV and XUV frequency combs can enable new applications in precision spectroscopy and metrology. For instance, a low-lying isomer transition of thorium around 150 nm is an excellent candidate for a nuclear clock [1] . Additionally, the precise measurement of the 1s-2s transition in He + can facilitate important tests of quantum electrodynamics. These are just two applications to name. One promising approach to generate the required deep UV and XUV combs is high-harmonic generation driven by a femtosecond, Yb-based high power laser-oscillator. The thin-disk oscillators are the simplest driving sources showing high reliability and stability.
