Optical and physical properties of fluorite crystals CaF2: Ce3 +, Yb3 +, Lu3 +

Abstract

The aim of the study is to investigate the optical properties of crystals as well as the parameters of thermal expansion, thermal conductivity, and the temperature coefficient of the refractive index. The data are very important in the development of optical laser systems. The parameters of thermal expansion and temperature coefficient of the refractive index were obtained by Jamin and Michelson interferometrs.
