超大尺寸KDP/DKDP晶体研究进展

KDP/DKDP晶体具有生长方法简单、成本较低、光学性能良好等优点,而可生长出的超大尺寸KDP/DKDP晶体是目前唯一可用于高功率激光工程的单晶材料。但是在晶体的生长过程中存在很多影响因素,同时对晶体进行后处理也会影响晶体的性能,这都直接关系到超大尺寸KDP/DKDP晶体的实际应用。鉴于此,本文综述了近些年超大尺寸KDP/DKDP晶体的重要研究进展, 特别是针对传统生长和快速生长中存在的问题和相应的解决对策以及晶体性能相关的研究,并重点对晶体的透过率、氘化率、激光诱导损伤等进行了分析和讨论。

Research Progress of Oversized KDP/DKDP Crystals

KDP/DKDP crystal has the advantages of simple growth method, low cost and good optical properties, while the oversized KDP/DKDP crystal is the only single crystal material that can be used in high power laser engineering. However, there are many factors in the process of crystal growth, and the post-treatment of crystal will also affect the performance of crystal, which is directly related to the practical application of oversized KDP/DKDP crystal. Accordingly, this paper reviews the important research progress of oversized KDP/DKDP crystals in recent years, especially for the traditional growth and rapid growth problems and the corresponding countermeasures as well as the properties-related of research, and the transmittance, deteration level and laser-induced damage of oversized KDP/DKDP crystals are analyzed and discussed with key point.
