Abstract: We present a complete frequency-domain description of electro-optic (EO) detection of terahertz (THz) electromagnetic radiation, including a description of the ellipsometry technique employed. These frequency-domain results show the effect of EO detection of a pulse of THz radiation as the product of three spectral filters acting on the complex amplitude spectrum of the THz pulse that is entering the EO crystal. For the usual experimental situation in which the optical bandwidth of the interrogating light pulse is small compared with the optical carrier frequency, we obtain an important simplification of our general result for the detected EO signal. When this simplified result is rewritten in the time domain, a more general description of the previous time-domain picture of EO detection is obtained.

TL;DR: This work studies high-harmonic generation in a bulk solid directly in the time domain, and reveals a new kind of strong-field excitation in the crystal that justifies the hope for all-optical band-structure reconstruction and lays the foundation for possible quantum logic operations at optical clock rates.
