Abstract

Summary form only given. To date, the measurement of terahertz pulse is primarily being carried out using ultrafast photoconductive antennas and far-infrared interferometric techniques. In this presentation, we report our recent work on ultrafast electro-optic field sensors for the coherent measurement of freely-propagating THz beams. The sensitivity of our ultra-wideband field sensors is improved to be comparable with the ultrafast photoconductive dipole antennas currently used.
