Light quenching effects at high-saturation conditions

Abstract

Abstract. Computer modelling of fluorescence light quenching is performed with no limitations on the optical wave intensities. The main attention is paid to searching for such combinations of polarizations of the interacting waves that provide minimal polarization changes for the waves passing through a cell. From the viewpoint mentioned above, the most appropriate case is circular polarization of the pumping wave. The efficiency parameter of amplification of the quenching wave can be used for checking mutual orientations of the dipoles responsible for absorption and emission. We show that the light quenching can produce appreciable changes in the polarization of fluorescence light passing through the cell.
