Electro-optic crystal mosaics for the generation of terahertz radiation

摘要

Apparatus for the generation of high energy terahertz radiation is presented and comprises laser means effective to produce subpicosecond optical pulses and a mosaic comprising a plurality of planar electro- optic crystals fastened together edge to edge in the form of a grid. The electro-optic crystals are in optical communication with the subpicosecond optical pulses, and behave as a single large electro- optic crystal, producing high energy terahertz radiation by way of optical rectification.
