| Abstract: | The conversion of optical radiation by dielectric microparticles with nanoinclusions of metal sols is theoretically studied. It is shown that, under resonance conditions, the concentration of nanoparticles inside a spherical microparticle affects the strength and structure of its internal field and influences the lasing conditions inside the microparticle. Two-mode lasing may occur depending on the concentration of nanoparticles due to overlap of the spatial structures of the fields of generated modes. |
