Laser-based Terahertz and Millimeter Wave Source
The invention relates to a method and a device for generating electromagnetic radiation in the terahertz and millimeter range, using a non-linear medium generating the indicated radiation by differential frequency generation within the laser resonator of a suitable laser, such as a VECSEL or a disc laser operating in two or more color modes. The invention further relates to novel decoupling structures used to this end for optimized decoupling and separating of the generated radiation from the optical radiation generated in the laser resonator, and suitable novel non-linear media as such.
