Overview of a tabletop setup for the generation of ultrashort XUV laser pulses for attosecond physics — •Felix Otten, Lars Englert, Marcel Behrens, and Matthias Wollenhaupt — Carl von Ossietzky Universität Oldenburg, Institut für Physik, Carl-von-Ossietzky-Str. 9-11, 26129 Oldenburg

Until recently, coherent X-ray sources such as free electron lasers or synchrotrons were available only for large research facilities. Due to new techniques in pulse generation, compression and amplification, ultrashort XUV light sources are now also available for small-scale laboratories. We present an overview of a tabletop setup for the generation of coherent XUV radiation in the attosecond regime based on high harmonic generation. The beamline consists of a commercial carrier-envelope-phase-stabilized IR femtosecond laser source with a hollow fiber compressor to provide few cycle driver pulses for the XUV pulse generation. We present initial results of the measured XUV spectra and give an outlook for future experiments on attosecond physics.
