Design of a system for conversion of the output of frequency tunable gyrotron into a Gaussian beam

摘要

In this paper we present a novel design of two quasi-optical systems for conversion of gyrotron outputs into gaussian beams. They consist of a quasi-optical antenna, focusing mirrors and a filter which removes the side lobes of the beam. One is capable to convert three TE1n mode outputs into Gaussian beams and the other is capable to convert three TE0n mode outputs into Gaussian beams.
