Abstract

An idea to search for a novel infrared NLO crystal from insulating compounds is presented. CsGeCl<SUB>3</SUB> has been synthesized by a modified route, and characterized by X-ray powder diffraction. This insulating compound with a room temperature conductivity of 5 X 10<SUP>-9</SUP> Scm<SUP>-1</SUP> (compressed pellet) has shown both excellent transparency in infrared region (0.4 - 20 micrometer) and SHG effect 4.5 times stronger than that of KDP.
