Coupled molecule-radiation field effects in an ammonia beam maser

Lefrere, Paul R

Abstract

Details are given of a number of phenomena which have been observed in an advanced ammonia beam maser. These include cooperative effects arising during the build-up of oscillations, regenerative nutation, pulling and quenching of oscillations, induced spiking, biharmonic operation in a magnetic field, hysteresis effects and polarization transients.
The relevance of each of these to other areas of quantum electronics is discussed.
