Paper Abstract

None of the existing spectrometer technologies currently fulfil the demands for larger IF-bandwidth up to 10 GHz for future THz heterodyne systems without using hybrid-solutions. At KOSMA (Koelner Observatorium fuer Sub-Millimeter Astronomie) we are investigating the idea of a laser side-band-spectrometer. We use laser modulation method to generate optical sidebands near of the laser frequency, which can then be frequency analyzed by standard optical methods like a high finesse Fabry-Perot (FP) etalon. First laboratory results of a prototype setup with 9 GHz Bandwidth will be presented.
