Application of Sm2Ti2O7 in technology of mirrors for He-Ne laser

Abstract

The technological regimes of production of the reflective coat with low energy losses for He-Ne laser mirrors have been worked-off on the base of environmentally safe film-forming material (FFM) Sm2Ti2O7 developed for high-refractive layers and convenient FFM SiO2. The experimental specimens of coat have been produced using the optimized technology. They are characterized by scattering factor σ = 0.010–0.015 %; absorption index к = 0.001–0.005 %. The optical characteristics of the obtained specimens have been studied.
