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. In the past, spectral measurements of the radiation were limited to the frequency range above 1 THz. Recently, first spectra were measured using a newly built polarizing Fourier-transform spectrometer which also covers the sub-THz regime. Studies of the temporal evolution of the spectrum during several revolutions of the energy-modulated electrons are presented. Furthermore, a setup currently being commissioned for electro-optical measurements of the THz field is discussed.
This project was funded by the BMBF under contract 05K16PEB.
