Abstract:

The purpose of the program was to produce coherent stimulated emission in the blue-green region in a purely organic dopant and host system. The theoretical analysis indicates that the short lived four-level fluorescent compounds are the most suitable materials for this purpose. A total of four fluorescent compounds were found with the appropriate spectroscopic characteristics. 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. An optically isotropic polymer was developed whose properties appear to be suitable as a host material for the fluorescing species. Two optical pumping systems were used 1 a modified Xenon lamp, and 2 an argon theta-pinch lamp. Some gain was observed in a liquid containing perylene as the active compound. This gain was observed at 4710 A and probably was due to preoscillation superradiance.
