Abstract

We report on the performance of a 4.7-THz local oscillator (LO) for the heterodyne spectrometer GREAT (German REceiver for Astronamy at Terahertz frequencies) on SOFIA (Stratospheric Observatory For Infrared Astronomy). The design of the LO and its performance in terms of output power, frequency accuracy, frequency stability, and beam profile as well as its implementation in GREAT will be presented.
