Abstract

The operation of a 92 GHz quasioptical gyrotron (QOG) having a resonator formed by a spherical mirror and a diffraction grating placed in a -1 order Littrow mount is presented. A power of 150 kW with a gaussian output pattern was measured. The gaussian content in the output was 98% with less than 1% of depolarization. By optimizing the magnetic field at fixed frequency, a maximum efficiency of 15% was reached.
