Paper Abstract

Statistical properties of speckles obtained using a narrow-band spectral selection of fluorescence from a coarse-grained dye-doped medium were experimentally studied. Silica powder doped by Rhodamine 6G solution and pumped by CW laser radiation at 532 nm was used as the sample medium. It was found that the speckle contrast falls down with an increasing fluorescence yield and rises up to the values close to the characteristic value for the Rayleigh distribution of speckle intensity at the edges of emission spectrum. This effect was interpreted in terms of the relationship between a path length distribution of fluorescence and its spectral decorrelation.
