Abstract
Radiative and photochemical properties of a number of laser dyes excited by focused radiation of a XeCl laser with intensity up to 200 MW cm(-2) were studied. A method for measuring the gain of organic molecules under high-po wer excitation is proposed. The dependence of the dye transmittance for the pump radiation on its intensity was studied. It is shown that changes in e nergy, spectral, and time characteristics of radiation and the photostabili ty of compounds under high-power excitation are associated with the formati on of superluminescence.
