Compact 1.9 THz BWO local-oscillator for the GREAT heterodyne receiver
چکیده انگلیسی

The 1.9 THz local-oscillator (LO) of the GREAT heterodyne receiver is presented. The LO is based on a frequency tripled backward-wave oscillator source. The frequency stabilization system is described and an astigmatic imaging system, developed for improved beam coupling, is presented. Allan variances and temperature dependent power drifts are analyzed. The LO is designed as a stand-alone system and fits into GREAT’s local-oscillator compartments. It produces more than 1.5 μW of stable output power to pump the hot electron bolometer mixers of the GREAT instrument.
