Phys. Rev. Lett. 96, 054801 (2006) [4 pages]Femtosecond Terahertz Radiation from Femtoslicing at BESSYReceived 1 December 2005; published 8 February 2006 Femtosecond far-infrared radiation pulses in the THz spectral range were observed as a consequence of the energy modulation of 1.7 GeV electrons by femtosecond laser pulses in the BESSY storage ring in order to generate femtosecond x-ray pulses (”femtoslicing”). In addition to being crucial for diagnostics of the laser-electron interaction, the THz radiation itself is useful for experiments where intense ultrashort THz pulses of well-defined temporal and spectral characteristics are required. © 2006 The American Physical Society URL:
