Light sources

We employ high-harmonic generation (HHG) to produce attosecond pulses by up-converting few-fs infrared radiation into the XUV and soft-X spectral region.

Advanced few-cycle optical parametric amplifiers are developed as optimal seed for soft-X high-harmonic generation.

Dispersion-engineered multipass cells are developed to compress high-power, high-repetition-rate Yb fiber lasers down to the few-cycle regime.

Ultrashort ultraviolet pulses are produced through gas-phase up-conversion for applications in ultrafast molecular spectroscopy.

Ultracompact four-wave mixing setups in the vacuum-ultraviolet spectral region are developed, for applications in Thorium nuclear spectroscopy as well as in ultrafast atomic and molecular physics.
