NOISE PROPERTIES OF MICROWAVE MASER OSCILLATORS.
Abstract
Rate equations describing transient behavior of the photon number of a maser oscillator exhibit damped sinusoidal solutions if longitudinal relaxation times are sufficiently long. The resonant nature of the transient is reflected in the shape of the noise power spectrum of the oscillator. The level of the noise can be described in terms of correlation functions satisfying differential equations. The form of the solutions of these equations allows one to interpret the oscillator noise in terms of a shot effect of the photon number and level populations. Experimental verification of the theoretical behavior has been carried out on a series of ruby microwave masers. The results obtained have been applied to establish limits of the sensitivity of ESR spectrometers utilizing maser oscillators. (Author)
