摘　　要：用降温法在不同的温度下快速生长KDP晶体,并测量其透过光谱、光学均匀性、金属杂质含量和光散射性能。结果表明随着生长温度的提高,KDP晶体的紫外光吸收和光散射点密度明显降低,但均匀性和杂质金属离子含量并无明显变化。KDP crystals were grown at different temperatures by rapid growth technique. Optical properties, including optical transmittance, optical homogeneity and light scatter of the crystals were measured. The results show that temperature has great effects on the optical properties of KDP crystals. With the rising of the growth temperature, the absorption of KDP crystals in UV region and the density of scatter in KDP crystals decrease greatly, but the homogeneities of the crystals and amount of impurieies of the metal in KTP do not have observable increase or decrease.
