Towards arbitrary shaping of THz pulses from a laser-electron interaction at DELTA — •Carsten Mai, Benedikt Büsing, Shaukat Khan, Daniel Krieg, and Arne Meyer auf der Heide — Center for Synchrotron Radiation (DELTA), TU Dortmund University

The TU Dortmund University operates the 1.5-GeV electron storage ring DELTA as a lightsource in user operation. In 2011, a short-pulse facility including a beamline for experiments with THz radiation was commissioned. Broadband as well as tunable narrowband radiation up to 6 THz is generated by an interaction of short laser pulses with a single electron bunch. The spectral profile of the THz pulses was controlled using a modulation of the spectral phase of the laser pulses. This was realized by employing a spatial light modulator as a phase shifter in the Fourier plane of the laser beam setup. Measurements of THz spectra shaped by laser modulation are presented.
