Abstract

The physicochemical characteristics, optical uniformity and photorefractive properties of a series of four LiNbO₃:Er:Zn single crystals have been studied. Single crystals have been obtained by the Czochralski method. The erbium content in the crystals was ~0.5 mol % and the zinc content in the crystals was ~4.02, 4.41, 4.65, 4.66 mol %. The dopant distribution in the LiNbO₃:Er:Zn melt—crystal system has been studied, and the optimal concentration ranges of erbium and zinc in the initial melt have been determined. The ranges provide crystals with high chemical, optical uniformity and resistance to optical damage for applications in optoelectronics and laser technology.

掺杂浓度对 LiNbO3:Er:Zn 单晶的光学均匀性和光折射特性的影响研究

研究了一系列四种 LiNbO3:Er:Zn 单晶体的物理化学特性、光学均匀性和光折射特性。单晶是通过 Czochralski 法获得的。晶体中的铒含量约为 0.5 摩尔%，锌含量约为 4.02、4.41、4.65 和 4.66 摩尔%。对 LiNbO3:Er:Zn 熔体-晶体体系中的掺杂剂分布进行了研究，并确定了初始熔体中铒和锌的最佳浓度范围。这些浓度范围提供了化学性质、光学均匀性和抗光学损伤能力都很高的晶体，可应用于光电子和激光技术领域。
