The operation of a 92 GHz quasi-optical gyrotron having a resonator formed by a spherical mirror and a diffraction grating placed in {minus}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{percent} with less than 1{percent} of depolarization. By optimizing the magnetic field at fixed frequency, a maximum efficiency of 15{percent} was reached.
