摘要

We have observed coherent synthesis of spatial profiles of THz radiation emitted from a photoconductive antenna array The antenna array is composed of seven independently addressable photoconductive antenna units having inter digitated electrodes The antennas were pumped by amplified 800 nm femtosecond optical pulses. Emitted THz radiation was focused, and the time-resolved spatial profile of the THz radiation on the focal plane was observed using a newly developed real-time imaging apparatus, which can correct the terahertz field images for nonuniformity in birefringence of the EO crystal By scanning the delay time, frequency-resolved images were also obtained, which exhibit frequency-dependent field profiles.
