Abstract

Calcium fluoride - CaF2 single crystals were grown using the Bridgman technique. By optimizing growth conditions, <111>-oriented CaF2, crystals up to 20 mm in diameter were grown. Number of dislocations in CaF2 crystals which were made by the method of Bridgman was 5×104 - 2×105 per cm2. In this paper we used XRD, Raman spectroscopy and the measurement of transmission in the mid IR-range to investigated structural and optical properties of obtained CaF2 single crystals..
