Paper Abstract

The dependencies of two-photon excited luminescence intensity on the exciting laser radiation energy have been studied. As a source of pumping light we have used Q-switched ruby laser, and luminescence has been recorded in the blue and near ultraviolet region. The experimental results have been obtained for some aromatic solid state compounds as anthracene, stilbene, POPOP and 3,4,5 trimethoxy benzoic acid. We have established essentially nonlinear behavior of investigated dependencies with saturation at the large pumping energy: 0.2 - 0.8 J. The opportunity of superfluorescence, appearing under two-photon pumping of aromatic solids, was analyzed.
