In this paper, KDP crystals were grown from an aqueous solution doped with different concentration of Fe^3+ dopant by traditional temperaturereduction method and "point-seed" rapid growth method. Furthermore, we examined the light scatter and measured the transmission of these KDP crystals. It is found that the dopant of Fe^3+ ion can improve the stability of the KDP growth solution when its concentration is less than 30 ppm. The effects of Fe^3+ ion on the growth habit and optical properties of KDP crystal are also obvious.展开更多
