Growth of SBN single crystals by Stepanov technique for photorefractive applications

The Stepanov technique has been developed for SBN solid-solution crystal growth. We carried out a comparison of the growth conditions of SBN crystals in the traditional Czochralski method and new growing technique. The advantages of the Stepanov technique for growing of pure and doped SBN crystals a...

Description
Summary:The Stepanov technique has been developed for SBN solid-solution crystal growth. We carried out a comparison of the growth conditions of SBN crystals in the traditional Czochralski method and new growing technique. The advantages of the Stepanov technique for growing of pure and doped SBN crystals are shown. They are high optical quality; definite form and sizes. High effective DPCM and high effective SPPCM were realized for SBN crystals doped with Ce. It was demonstrated that SBN doped with Cr and Co are promising photorefractive materials with short response time.
