Key accomplishments during this period are 1 The successful demonstration of a new technique for generating subpicosecond electromagnetic pulses using large aperture photoconductors to produce directional and diffraction-limited beams of terahertz radiation 2 The development of a new electrically-controlled phased array of photoconducting antennas for producing steerable terahertz radiation 3 The extraction of femtosecond electromagnetic pulses from an electro-optic crystal following their generation by electro-optic Cherenkov radiation, and their subsequent propagation and detection in free space 4 The measurement of subpicosecond electrical response of a new organic electrooptic material polymer 5 The observation of terahertz transition radiation from the surfaces of electro-optic crystals.
