Studies on L-cystine hydrobromide single crystals for nonlinear optical applications

Abstract

L-cystine hydrobromide (LCHBr) is a novel nonlinear optical material which has been synthesized and grown. The low-temperature solution growth technique was employed to grow the single crystal of LCHBr. The structure of the grown crystals was characterized by single-crystal XRD. The different functional groups of the grown LCHBr crystal are studied using FTIR spectroscopy. The transparent nature of the grown crystal was analysed by UV-Vis-NIR study. The mechanical strength of the grown crystal was analysed using microhardness study. The optical second harmonic generation conversion efficiency of the LCHBr crystal was studied using Nd:YAG laser. The laser damage threshold value of this grown crystal has been evaluated.
