The lasing thresholds comparison in active medium microlayers with metal and dielectric nanoparticles

摘要

It is experimentally shown, that the introduction of agglomerated metal and dielectric nanoparticles with a concentration of the order 10 cm into the ethanol solution of R6G with 20 microns thickness of microlayers decreases the threshold lasing by about two orders of magnitude compared with the threshold of stimulated emission in a microlayer of pure ethanol solution R6G.
