The 1.5-GeV synchrotron light source DELTA, operated by the TU Dortmund University, provides femtosecond pulses in the VUV regime using the coherent harmonic generation (CHG) technique. A laser-induced energy modulation of electrons in a thin slice of the electron bunch is converted into a density modulation corresponding to the laser wavelength, which gives rise to coherent radiation at harmonics of the laser wavelength. Measurements with a single-shot spectrometer based on a gated image-intensified CCD camera were carried out in order to better understand and optimize the CHG radiation. Furthermore, a proof-of-principle pump-probe experiment employing the CHG radiation has been performed.
