Abstract
In order to show that the presence of nonresonant optical fields near the surface of the agglomerates of nanoparticles may lead to decrease of lasing dye energy threshold of superluminescence and increase its efficiency. The superluminescence was studied experimentally in a thin layer of laser dye R6G with nanoparticles of Ag, Al, Ni, without manifestations of random laser medium and the effect of the plasmon resonance.
