Abstract

Recent experimental and theoretical investigations in the field of new semiconductor sources of coherent terahertz radiation based on the intracavity nonlinear mixing of close-in-frequency optical fields in dual-wavelength diode lasers are reviewed. Perspective schemes of suggested generation of submillimeter and far-infrared radiation in quantum-well heterolasers are considered. The ways of increasing the power of difference-frequency radiation by means of mode-locked lasers and hybrid surface-emitting grating-outcoupled lasers are discussed.
