Tuneable dual-OPCPA system from deep UV to Mid-infrared for ultrafast spectroscopy

We will present a versatile design of a tunable high-power dual-output OPCPA system, with one output operating in visible and near-IR spectral regions, and one output operating in the mid-infrared spectral region. The tunability range can be further extended to 200 nm (6 eV) in the deep UV and 5 µm in mid-IR by adding harmonic generation, nonlinear spectral broadening, and difference-frequency generation modules. Combining different compression schemes, we achieve pulse durations below 50 fs within most of the tunability range. The design can be adapted to different femto- and pico-second Yb-based pump-laser architectures, including but not limited to InnoSlab, thin-disk and bulk-crystal regenerative amplifiers.
