Development of Methods for Growing LiIO3 and Ba(NO3)2 Crystals as Materials for Laser Frequency Converters

Abstract

New methods for growing LiIO₃ and Ba(NO₃)₂ crystals have been developed. Barium nitrate crystals up to 12 × 12 × 100 mm³ in size and lithium iodate crystals up to 120 × 120 × 200 mm³ in size of necessary optical quality are obtained. The influence of рН on the morphology of Ba(NO₃)₂ growth faces is investigated. The data on the morphology of the {111} and {\(\bar {1}\bar {1}\bar {1}\)} faces of crystals grown at different solution acidities are obtained by atomic force scanning microscopy. The possibility of fabricating optical elements from LiIO₃ crystals of ~100 × 100 × 100 mm³ in size is shown.
