Paper Abstract

A hypothesis of a multifold reduction of exited particle lifetime at supersaturated pump fluxes, suggested in /1-7/ for accounting for an unusual growth of dye fluorescence intensity at high pump fluxes, is analyzed. Registration of profiles of pump and fluorescence pulses of phenolemine F-510 in ethanol solution with lifetime of exited particles τ= 6.6 ns was made with pump fluxes IO = (1023 - 1027) cm-2s-1 at a wavelength of 532 nm. The experimental results testify for preservation of the exited particle lifetime τ= 6.6 ns at high pump fluxes.
