Efficiency Increasing of Laser Technologies Application for Identification of Art and Industrial Products

Usoltseva, A. V.

Abstract.The relation between properties of industrial products and individual characteristics of the laser technology production was researched. The analytical expressions for calculating of the depth of penetration of laser radiation into the material are derived in this paper; these expressions allow to in-crease the efficiency of laser technologies application, to choose optimal laser parameters, and to consider microstructure, chemical composition and mechanical properties of the material. The solution of topical problem of technological modes establishing is proposed, considering multiple versions of technology and laser equipment choices and considering indeterminacy of thermal properties of material. The complex index is distinguished, that index greatly simplifies selection of laser radiation parameters and allows to make atlas of materials thermal diffusivities.
