Design of a quasi-optical system for conversion of TE/sub 0n/ mode outputs of a gyrotron into Gaussian beams

摘要

Presents a novel design of a quasi-optical system for conversion of gyrotron outputs into gaussian beams. It consists of a quasi-optical antenna, four focusing mirrors and a filter which removes the side lobes of the beam. The system is capable of converting three TE/sub 0n/ mode outputs into Gaussian beams.
