Paper Abstract

A method of photostability examination of dye active media is described. Quantum yield of phototransformation, relative yield of some final photoproducts, as well as laser lifetime of 2- (4pyridyl)-5 phenyl)oxazole (4PyPO) ethanol solutions were measured. These characteristics were studied as functions of dye concentration, excitation power, and pulse duration, as well as type of irradiation (by means of spontaneous or lasing). Transient T-T absorption spectra were monitored. Effects of different additions into solution of T-T absorption and photostability of the medium were investigated. Improvement in lifetime of 4PyPO active media is discussed.
