Abstract

The present invention relates to a device for creating and coherently detecting terahertz radiation, comprising a laser light source (1), a transmission antenna (2) that can be activated by the laser light source (1) for creating the terahertz radiation, and a receiver with a receiver antenna (3) that can be activated by the same laser light source (1), wherein the transmission antenna (2) comprises a photo diode as a light-sensitive element and the receiver antenna (3) a fast photo-conductor as a light-sensitive element. The invention further relates to a use of such a device for analyzing a sample.
