Abstract

Characteristics of cavityless lasing in thin layers of rhodamine 6G (R6G) solutions doped with aluminum, silver, and aluminum oxide agglomerated nanoparticles are experimentally investigated. It is demonstrated that the agglomerates of Ag, Al, and Al2O3 nanoparticles in R6G solutions lead to a significant (by more than two orders of magnitude) decrease of the cavityless lasing threshold in a wide range of concentrations of the agglomerates compared to the luminescence threshold in R6G solution without nanoparticles.
