Abstract

Terahertz (THz) pulses with energies up to $100\mathrm{\mu J}$ and corresponding electric fields up to $1\mathrm{MV}/\mathrm{cm}$ were generated by coherent transition radiation from $500\mathrm{MeV}$ electron bunches at the free-electron laser Freie-Elektronen-Laser in Hamburg (FLASH). The pulses were characterized in the time domain by electro-optical sampling by a synchronized femtosecond laser with jitter of less than $100\mathrm{fs}$. High THz field strengths and quality of synchronization with an optical laser will enable observation of nonlinear THz phenomena.
