摘　　要：KDP晶体是典型的水溶液型人工晶体。它具有非线性光学性能优良、易于生长出大尺寸单晶的优点,被用来制作惯性约束核聚变(ICF)工程中的倍频器件。但大晶体在生长过程中容易出现开裂、包藏等缺陷,严重影响晶体的物理性能。为了生长出高质量单晶,针对KDP晶体的生长机理研究与生长工艺改进工作一直在进行。在此背景下,本文总结了近半个世纪以来针对该晶体生长机理研究的主要实验手段,分别介绍了它们的工作原理及存在的优缺点,并对部分研究结果进行了整理,可为其他水溶液型晶体生长机理研究工作提供有用参考。KDP crystal is a typical artificial crystal and be grown in an aqueous solution.It has excellent nonlinear optical properties and can be easily grown into large-size single crystal.The frequency-doubling devices in the project of inertial confinement nuclear fusion(ICF)were made from it.However,cracks and inclusions are easy to occur during the growth process of large crystals,which can affect the physical properties of crystals.The exploration of the growth mechanism and the improvement of growth technology of this kind of crystal have been carried out.In this context,this paper summarizes the main research methods on the growth mechanism of KDP crystal in the past half century and compares their advantages and disadvantages.Besides,the related research results are introduced.This paper can provide a reference for other studies on the growth mechanism of aqueous solution crystals.
