FIELD: laser treatment of materials. ^ SUBSTANCE: method can be used for treatment of materials accompanied by change in physical properties of materials in the zone being close to surface. Method is based upon influence of coherent polarized pulse laser radiation onto sub-surface layer of material to provide excitement of surface phonon-polaritons, which interact with the layer to form interference pattern. Relief lattice is recorded is recorded in such a way that change in real part of refractivity of boundary is provided for surface phonon-polaritons. The change results in formation of permittivity lattice in sub-surface layer of material. ^ EFFECT: reliability; reproducibility; stability. ^ 14 cl, 4 dwg |
