Impact of impurities on the α-LiIO{sub 3} crystal growth: Technique for measuring the “dead zone”
- Russian Academy of Sciences, Institute of Applied Physics (Russian Federation)
Lithium iodate (α-LiIO{sub 3}) single crystal is a promising nonlinear optical material, which used for efficient laser radiation conversion in the visible and near-IR regions. A technique for measuring the “dead zone” (ΔТ{sub dz}) of LiIO{sub 3} solutions has been developed; data on the impact of Fe(IO{sub 3}){sub 2}, AgIO{sub 3}, CsOH, H{sub 3}PO{sub 4}, and methyl methacrylate on the growth of the (100) face of α-LiIO{sub 3} crystals have been presented; and the dependences of the nucleation and motion of single steps on the degree of supersaturation have been measured. It is shown that the ΔТ{sub dz} value makes it possible to estimate the validity of solutions for growing α-LiIO{sub 3} crystals. The results of measuring the face growth rates and step velocities for KDP and α-LiIO{sub 3} crystals are compared.
