Ultrabroadband terahertz pulses:: generation and field-resolved detection

In this paper, we discuss the latest techniques for the generation and field-resolved detection of tunable femtosecond electromagnetic field transients in a spectral regime covering the complete mid-infrared frequency range. In particular, we review the generation scheme based on phase-matched optical rectification. We also present a novel detection method, exploiting phase-matched electro-optic sampling, which extends the accessible frequency range towards the near-infrared.
