Photoemission spectroscopy using high-order harmonics driven by a MHz fiber laser — •Cheng-Tien Chiang1,2, Michael Huth1, Andreas Trützschler1,2, Jürgen Kirschner1,2, and Wolf Widdra2,11Max-Planck-Institut für Mikrostrukturphysik, Weinberg 2, D-06120, Halle(Saale), Germany — 2Institute of Physics, Martin-Luther-Universität Halle-Wittenberg, Von-Danckelmann-Platz 3, D-06120, Halle(Saale), Germany

We report a laboratory photoemission setup using high-order harmonic generation (HHG) as a light source driven by a fiber amplifier laser system at MHz repetition rate. The HHG light source consists of a compact generation chamber and a monochromator. Output of the fiber laser is expanded and focused in a tight focusing geometry into an argon or a xenon gas jet, producing vacuum ultraviolet light with photon energy from 16 to 40 eV. With this light source in combination with a time-of-flight electron spectrometer we demonstrate photon energy dependent photoemission experiments on a Ag(001) surface. Technical details of the setup will be presented.
