Frequency Stability of Maser Oscillators Operated with Enhanced Cavity Q

Abstract

This paper presents an experimental study of the short term frequency stability of masers equipped with an external feedback loop to increase the cavity quality factor. The frequency stability of a hydrogen and a rubidium maser are measured and compared with theoretical evaluation. It is observed that the frequency stability passes through an optimum when the cavity Q is varied. Long term fluctuations are discussed and the optimum mid-term frequency stability achievable by small size active and passive H-masers is considered.
