摘要: This study experimentally demonstrates lasing mode switching within a ZnO nanoparticle film coated onto magnetic thin of NiFe alloy. When neodymium magnet is brought close to or moved away from the film, behavior observed in modes, although such change not induced on glass substrate. Our results suggest that changes modes are because magneto-optical effect at surface film. The would be enhanced by localized fields near surface, inducing suppression enhancement response surrounding environments, and accounting for switching.
