AROMATIC ORGANIC LASER DEVELOPMENT.
Abstract
The purpose of this study was to produce coherent stimulated emission in the blue-green region in a purely organic dopant and host system. Toward this end, a theoretical analysis of the problem was made and experimental work on the development of such a laser was done. The theoretical analysis indicates that the short lived four-level fluorescent compounds are the most suitable materials for this purpose. The principal experimental difficulties included the development of a suitable host material in which the absorbing and scattering losses are kept to a minimum and an optical pump system capable of efficiently producing several megawatts of absorbable peak power in a short time. Some gain at 4710 Angstroms in a Fabry-Perot resonant cavity was observed which is probably preoscillation superradiance. This report is divided into four major segments which includes the theoretical analysis, the materials selection and preparation, the device development, and the experimental pumping results obtained to date.
