摘要
磁光材料是指从紫外到红外波段具有磁光效应的光功能材料,按照材料的类型可将其分为磁光玻璃、磁光晶体、磁光透明陶瓷等。其中,磁光透明陶瓷是近年来出现的一种新型磁光介质材料,具有高Verdet常数、大尺寸、高热导率、高激光损伤阈值等优点,因而是用于高功率激光器中法拉第隔离器最理想的材料之一。目前已经报道的磁光透明陶瓷材料主要包括铽镓石榴石(Tb_3Ga_5O_(12),TGG)陶瓷、铽铝石榴石(Tb_3Al_5O_(12),TAG)陶瓷以及一些倍半氧化物陶瓷,如氧化铽(Tb_2O_3)陶瓷、氧化钬(Ho_2O_3)陶瓷、氧化镝(Dy_2O_3)陶瓷等。本文首先介绍了几种常见的磁光效应,详细阐述了法拉第效应和克尔效应的基本原理。着重对几种磁光透明陶瓷材料的研究进展、材料性能、应用前景进行了综述和介绍,并对这几种磁光透明陶瓷的性能进行了比较和分析,指出了它们存在的问题和今后的研究方向。
Magneto-optical material is a kind of optical functional material which has the magneto-optical effect from ultraviolet to infrared band. According to the type of material, magneto-optical materials can be classified into magneto-optical glass, magneto-optical crystals, magneto-optical transparent ceramics, etc. As a new type of magneto-optical material which has emerged in recent years, magneto-optical transparent ceramics are considered as one of the most promising candidates for Faraday isolators used in high power lasers due to its high Verdet constant, large size, high thermal conductivity, and high laser-induced-damage threshold. Up to now, the magneto-optical transparent ceramics reported mainly include terbium gallium garnet （Tb3Ga5O12, TGG）, terbium aluminum garnet （Tb3Al5O12, TAG） and some sesquioxide ceramics such as terbium oxide （Tb2O3）, holmium oxide （Ho2O3）, dysprosium oxide （Dy2O3）, etc. In this paper, several common magneto-optical effects were briefly introduced, and the basic principles of Faraday effect and Kerr effect were illustrated in detail. In addition, the research progress, all-sides properties and application prospects of magneto-optical transparent ceramics were mainly reviewed. The properties of different kinds of magneto-optical transparent ceramics were compared and analyzed, and the existing problems as well as the research prospects were also proposed.
