Our group performs basic research in coherent and strong field interactions of lasers with matter. This research involves the use of ultrafast and ultra-intense lasers for the generation of laser-driven short-pulsed light sources producing extreme ultraviolet wavelengths. The main conversion process we study is the generation of high-order harmonic radiation. Investigating the properties of this unique light source allows studying ultrafast dynamics on atomic and molecular timescales (attoseconds / femtoseconds) as well as structural imaging down to sub-nanometer spatial resolution.
Our current projects deal with investigations on the nonlinear dynamics during filamentary propagation of intense laser pulses, harmonic generation from liquid water droplets, and the nonlinear conversion processes from plasmonic field enhancement in nanostructures.
