Generation of High Harmonics with 100 µ J Femto Second Pulses at 100 kHz Repetition Rate — •Philipp Klaus1, Martin Laux2, Christian Ott2, Maksim Kunitski1, Robert Wallauer1, Thomas Pfeifer2, and Reinhard Dörner1 — 1Institut für Kernphysik, Goethe Universität, Frankfurt, Deutschland — 2Max-Planck-Institut für Kernphysik, Heidelberg, Deutschland
The setup for the generation of high harmonics (HHG) using the output of an amplified Ti:sapphire laser with a repetition rate of 100 kHz will be presented. High harmonic generation with a high repetition rate is rather challenging since the pulse energy is limited, in our case to 100 µ J. Usually pulse energies lie in the mJ range. The high repetition rate is however desirable for coincidence single molecule studies on gas and solid-state targets. First tests of the HHG setup with Ar gas showed a total harmonics yield of 4· 109 photons per second.
