RESEARCH AND INVESTIGATION OF MATERIALS FOR LASER APPLICATIONS
ELECTRO-OPTICAL SYSTEMS INC PASADENA CALIF
Various rare earth chelates, organic compounds, and other materials suitable for laser application were synthesized. The relevant parameters like the absorption and fluorescence spectra, the fluorescence decay time, fluorescence efficiency, photo and thermal stability are being evaluated. Some of the promising materials were tested for lser action. No laser action was observed in these materials. Neodymium ethylacetoacetate was synthesized, and exhibited a fluorescence of high intensity. From a survey of different glasses as host material, it was found that the rare earth introduced as a fluoride and in a high temperature, high silicate glass gives the highest fluorescence and longest decay times.
