Results of studying the absorption coefficients and refractive indices of PbTe and GeTe films in the spectral range from 1 to 15 μm are presented. The optical constants of films were found by a technique that combines calculation methods and the pre

Films of fluorides may crystallize during vacuum deposition on substrates that leads to undesirable diminishing of transparency of films (having optical thickness more than 3 ÷ 5 μm) for the visible spectral range. To solve this problem we carried

The main requirement of stable work of tunable lasers is the constancy of reflection coefficient for laser mirrors in the necessary spectral range. In order to synthesize and make mirrors for IR-range we elaborated multilayer film structures of two k

The phase distortion's influence on the radial luminosity of the laser radiation in distant zone occurred in mirrors with radial reflection coefficient has been investigated. It was shown that the radial luminosity diminished 1.5 - 2 times in compari

To obtain wide-band antireflection coatings for the visible and the middle IR regions of the spectrum transparent optical films with different refractive indexes and small absorption coefficients are required. Promising BaF 2 , CaF 2 , SrF 2 films wi

This paper describes examples of the synthesis and fabrication of optical coatings that operate in the mid-IR region and the visible region simultaneously. In particular, it tells how to separate the radiations of CO2 and He-Ne lasers by means of int

Fluoride films (made from barium, calcium, strontium, and lead fluorides) tend to crystallize when they are sputtered. For an optical thickness more than 3-5 µm, their transparency in the visible region decreases because of losses to scattering. Thi
