通过传统降温法,利用不同原料从氘化程度为85%的溶液中生长DKDP晶体并对加工样品进行了相关测试。研究了不同原料对DKDP晶体的生长和光学性能的影响。实验表明:采用高纯原料所得DKDP晶体的光学性能提高,但其晶体生长容易出现外扩现象。
In this paper, DKDP crystals were grown from 85%-deuterated solution by traditional method of different materials. Then some of those crystals were chosen to measure their optical properties. It was found that the optical property of DKDP crystal grown from purer material was obviously improved, but expansion often occurred at the DKDP prismatic faces.
