【摘要】 本文报导了GGG:Nd³⁺单晶的生长研究、完整性观测和性能测试。研究了如何控制组分过冷、铱包裹物和位错等缺陷。报导了这些缺陷的光学观测,并测定了GGG:Nd³⁺单晶中的Nd³⁺的平均分布系数、晶体点阵常数、激光效率和光的透过率等。对缺陷的观测、控制和性能的测定都围绕着这样一个问题,即GGG:Nd³⁺单晶能否既作为具有磁光效应的外延膜的基片材料,又同时作为发生激光的工作物质。实验结果认为这将是可以实现的。从而提出这样一个看法,GGG:Nd³⁺的这两种功能将有助于某些磁光器件的研制,有可能使这两种作用结合在同一块材料上,使器件固体化、简单化。更多还原

【Abstract】 The article deals with the growth of GGG:Nd³⁺ single crystals, the determination oftheir properties and crystal perfection including the control of constitutional supercooling,irridium inclusions and crystal defects of dislocation, etc.The observation of defects byoptical method and the determinations of the distribution coefficients of Nd³⁺ in GGG:Nd³⁺crystal, the crystal lattice constants, the lasing efficiency and the optical transmission aredescribed.The purpose of these measurements was to see if GGG:Nd³⁺ single crystals can beused both as the substrate of a magneto-optic film and as a laser rod.Experimental resultsgave a positive answer, from which it seems that these two properties of the GGG:Nd³⁺crystal may be useful in the investigation of magneto-optical devices and there may be pos-sibility to combine the two functions onto one block of material thereby the device is sim-plified.更多还原
