Multi-turn Spectral Observation of Coherent THz Pulses at DELTA — •Carsten Mai, Fin Hendrik Bahnsen, Max Bolsinger, Fabian Götz, Svenja Hilbrich, Markus Höner, Marc Andre Jebramcik, Shaukat Khan, Nils Lockmann, Arne Meyer auf der Heide, Robert Molo, Raffael Niemczyk, Gholamreza Shayeganrad, Peter Ungelenk, and Dennis Zimmermann — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

Coherent ultrashort THz pulses induced by a laser-electron interaction are routinely produced and observed at DELTA, a 1.5-GeV synchrotron light source operated by the TU Dortmund University. The radiation spectrum is known to shift to the sub-THz regime after the initial laser-electron interaction. At a dedicated THz beamline, measurements using a polarizing Fourier-transform spectrometer have been performed in conjunction with an ultra-fast Schottky-diode detector. Studies showing the spectral evolution after several revolutions and further measurements are presented.
