Spectrotemporal shaping of laser-induced THz pulses at the DELTA storage ring — •Carsten Mai, Benedikt Büsing, Shaukat Khan, Daniel Krieg, and Arne Meyer auf der Heide — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany
At the 1.5-GeV electron storage ring DELTA, operated by the TU Dortmund University, a broadband source for coherently emitted (sub-)THz radiation was commissioned in 2011. The generation of both broadband and narrowband radiation is based on an interaction of short laser pulses with electron bunches in the storage ring. To enhance a narrowband spectral content, a periodic intensity modulation is applied to the laser pulses employing the chirped-pulse beating technique. The use of a spatial light modulator promises to allow a more flexible control of the laser pulse shape and the spectrotemporal properties of the resulting THz pulse.
