XUV Laser Physics - Junior Research Group
Our group provides 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-pulse 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.
Generation of high-power femtosecond pulses at 88 nm
Phase-matching of high-order harmonics in a semi-infinte gas cell
The generation of high-order harmonics in a semi-infinite gas cell is investigated in a systematic manner. We study the phase-matching for this geometry depending on the focus position and gas pressure. [more...]
High-order harmonic generation after pulse compression in a filament
In this research field generate ultra short pulses after filamentation in argon and compression by double chirped mirrors. These pulses are used to generate high-order harmonics in a semi-infinite gas cell in different noble gases. [more...]
High-order harmonic generation in a dense medium
The interaction of intense laser pulses with dense media is a promising field of research. Our group has therefore set up an experiment creating a determinate series of liquid droplets as target to study nonlinear processes in laser-matter interaction, such as high-order harmonic generation.
