Abstract

A radiation source for emitting terahertz radiation (6) is specified, comprising at least two laser light sources emitting laser radiation (11, 12) of different frequencies, and a photomixer (5) comprising a photoconductive semiconductor material (51) and an antenna structure (52), the photomixer (5) being configured to emit the laser radiation (11, 12) of the laser light sources (1, 2) and emitting terahertz radiation (6) with at least one beat frequency of the laser light sources, and wherein the at least two laser light sources are surface-emitting semiconductor lasers (1, 2) which are arranged in a one-dimensional or two-dimensional array on a common carrier (10).
