Abstract
The effect of fluorescence saturation under laser pulsed excitation appears as a non-linear response of emission signal versus intensity of excitation. The saturation becomes important when the rate of molecular excitation exceeds the rate of their deactivation. Typically the effect is noticeable when excitation photon flux ((rho) ) exceeds 1023 . . . 1024 cm-2s-1. We present the theory of fluorescence saturation under laser pulsed excitation for both quasi-stationary and non-stationary cases, as well as the experimental study on fluorescence saturation for of organic dyes in aqueous and ethanol solutions and in polymer film.
