Abstract

The technology of obtaining the interference coatings for the nonlinear crystals has some peculiarities depending on the specific properties of these crystals. Temperature, pressure of reactive gas and energy of charged particles do not affect principally the optical properties of the nonlinear crystal. In this paper the various aspects of thin dielectric films for crystals are presented. There are calculations of the optimum structure of the optical coating for specific spectral region, obtaining the required parameters of the films having the optical properties that would not impair the own properties of the crystal parameters of the films having the optical properties. As a rule, the coatings of these crystals that could be coated without heating in a vacuum chamber. As the result of this work the various types of the interference coatings have been obtained. There are the AR coating at a single wavelength in the spectral range of 0.24...1.5 micrometers , the broad-band AR coatings, the AR coating with two AR spectral regions simultaneously.
