Coherent Harmonic Generation at DELTA — •Arne Meyer auf der Heide, Svenja Hilbrich, Markus Höner, Holger Huck, Maryam Huck, Shaukat Khan, Carsten Mai, Robert Molo, Helge Rast, Andreas Schick, and Peter Ungelenk — Center for Synchrotron Radiation (DELTA), TU Dortmund, 44227 Dortmund, Germany

At DELTA, a 1.5-GeV synchrotron light source at the TU Dortmund University, Coherent Harmonic Generation (CHG) is under commissioning and shall soon be used for pump-probe experiments. CHG is based on the interaction of ultrashort laser pulses from state-of-the-art laser systems with electron bunches in an undulator to generate short and coherent pulses at harmonics of the laser wavelength. The CHG pulses are characterized by different methods, e.g. studying the transverse and longitudinal coherence with a classical double-slit experiment and a Michelson interferometer, respectively. The first pump-probe applications will be devoted to the study of ultrafast magnetic phenomena with sub-picosecond time resolution.
