FUNDAMENTAL STUDIES OF THE COHERENCE PROPERTIES OF ELECTROMAGNETIC RADIATION.

Abstract

Theoretical studies have been made of the quantum mechanical description of coherence in materials such as ferromagnets and superconductors and of electromagnetic radiation. In the latter studies, application has been made to effects of coherence and high power on photodetection. A practical result is that the photon echo measurement is shown to provide a sensitive detector of coherence. Experimental work has been carried out to determine the diffusion coefficients and spin depolarization cross sections of optically pumped alkali vapors in noble buffer gases. A method has been developed to measure the density of cesium vapor as a function of temperature. (Author)
