36 GHz Travelling Wave Maser

Nature volume 218, page 158 (1968)Cite this article

Abstract

AMPLIFICATION of 6 dB has been obtained in a travelling wave maser at 36 GHz using Cr+3 doped rutile (TiO2) as the active material. The slow wave structure is a fully filled wave guide with the crystal orientation designed for push–pull pumping and double ion site operation. A superconducting magnet operating in the persistent mode provides the direct current magnetic field.
