摘要
研究了几类可能出现在KDP晶体的生长溶液中的有机物杂质和无机阴离子杂质基团对KDP晶体散射、透过率、光损伤阈值等光学质量的影响,结果表明,不同种类的杂质的影响并不相同,造成这一结果的根本原因在于杂质离子的结构及其与晶体表面原子成键能力的不同。
Effects of certain impurities, which exit in growth solution of KDP crystal, on optical qualities of KDP crystal are investigated. The results show that the effects of different kinds of impurities are not the same. The reason can be ascribed to the chemical structure and chemical bonds between the impurities and surface atoms of KDP crystal are different. Those impurities have similar structure and easy to form H bonds with [H2PO4]-, such as pyrophosphate and sulfate affect pyramidal sector of KDP crystal easily while the other impurities, such as Cl- have no evident effect on the growth and properties of KDP crystals.
