Abstract

Pulsed microwave radiation in a tuning range from 10 to 30 GHz has been generated through the parametric interaction of two near-infrared pulses in GaP crystals at low temperatures. The power of the microwave pulses (duration 30 nsec) was of the order of 1 mW. The pump pulses were generated with a Nd:YAG laser emitting simultaneously at two frequencies, within the bandwidth of the 1.064-microm transition, as a result of an étalon output coupler.
