生长方法对DKDP晶体生长习性及光学性能的影响
EFFECTS OF GROWTH METHOD ON THE GROWTH HABIT AND OPTICAL PROPERTY OF DKDP CRYSTALS
摘要
Abstract
Deuterated potassium dihydrogen phosphate((K(D_xH_(1-x))_2PO_4,DKDP)crystals were grown from deuterated aqueous solution with 85%(in mole)deuterium and KH_2PO_4 as raw material by using the traditional temperature-reduction method and point-seed rapid growth method, respectively. The optical properties of DKDP crystals were investigated by light scattering and transmittance spectra. The results indicate that, by using the point-seed rapid growth method, the growth speed rate of DKDP is ten times greater than that by using traditional temperature-reduction method. But the light scattering of the DKDP grown by the point-seed rapid growth method becomes more serious, and its transmittance also decreases evidently as the growth speed rate increases. Moreover, the optical property of the prism sector in the DKDP deteriorates obviously compared that with the pyramidal sector.关键词
