FIELD: electricity.
SUBSTANCE: generator of subteraherz and teraherz emission includes a laser emission source, an electrical circuit with voltage sources and an impedance load, and an optically active element. The latter is provided with an additional field transistor provided in a gate area with a semiconductor layer with a short life time of photoexcited charge carriers, a gate of transparent or semi-transparent material; electric displacement is supplied to a sink and to a source of a conductive channel of the field transistor.
EFFECT: increasing output power.
