Abstract:
The saturation of the spectral quality of the fluorescence response of randomly inhomogeneous media to external laser pump with intensities above the random lasing threshold in a medium has been studied. It has been found that the saturation of the fluorescence spectral quality is due to a decrease in the fluorescence enhancement length in the medium to the minimum value determined by the average size of local fluorescence emitters associated with laser speckles and by radiative exchange between emitters.
