Lasing in a thin layer of luminophor with metal nanoparticles agglomerates

Abstract

In order to show that the presence of high optical fields near the surface of the agglomerates of nanoparticles may lead to lower of lasing dye energy threshold and increase its efficiency, lasing 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.
