摘要：In this paper, the optical properties of deuterated potassium dihydrogen phosphate (DKDP) crystals with deuterium content of 55, 65 and 70% grown by traditional temperature-reduction method are studied, including weak absorption, non-uniformities of refractive indices, 3 conversion efficiency and the 3 laser damage threshold (3 LDT). The results indicate that the weak absorption of 70% DKDP crystal is smaller than that of 55 and 65% DKDP. The result of non-uniformities of refractive indices is further confirmed that the variation of deuterium content has little effect on the homogeneity of DKDP crystals. The 3 conversion efficiency is measured under the optimum phase matching angle and 3 conversion efficiency of 70% DKDP crystal is the highest, which achieved 50%. The results indicate that 3 LDT of 70% DKDP crystal is slightly higher than that of 55 and 65% DKDP.
