Abstract

A new output coupling scheme for Fabry-Perot resonators, consisting of a diffraction grating placed in Littrow mount has been proposed [1]. A hot-test at 92 GHz has been performed in a quasi-optical gyrotron (Q0G) of the Centre de Recherches en Physique des Plasmas. The coupler was designed so that the output beam can be matched to a 2.5 inche HE 11 guide at the gyrotron window. An IR camera was used to determine the characteristic of the pattern at the window. The results show that it is gaussian. The measured spot-size corresponds to the design values.
