FIELD: optics. SUBSTANCE: optical material to control parameters of electromagnetic radiation comprises particles with characteristic size less than wave length and depth of penetration of radiation into material of particle. Particles are produced from material having negative actual part of dielectric permittivity, have polarizability exceeding resonance polarizability of individual atom and are positioned in matrix amplifying electromagnetic radiation. EFFECT: development of optical material with high and controlled refractive index in spectral region with lack of absorption, with high amplification and non-linearity. 5 cl, 4 dwg
