Abstract
Freely propagating THz pulses are detected in electro-optic (eo) cryst als by monitoring the phase retardation (PR) of an infrared femtosecon d probe pulse. This technique permits the determination of the tempora l shape of the THz pulse in the subpicosecond time domain. We present measurements in LiTaO3, LiNbO3, and ZnTe and compare their signal perf ormance as eo crystals with theoretical calculations for the PR signal . ZnTe shows the best performance for eo detection. (C) 1997 American Institute of Physics.
