New heavy metal oxide glasses as nonlinear photonic materials

International audienceNew Heavy Metal Oxide Glasses have been analysed for their excellent optical properties and their application in nonlinear optics. More specifically, chloro-antimonite glasses have been obtained in the Sb2O3-PbCl2-AgCl ternary system. Thermal, optical and mechanical properties have been studied. The silver chloride concentration was increased at the expense of antimony oxide according to the following composition rules: (80-x)Sb2O3-20PbCl(2)-xAgCl; (70-x)Sb2O3-30PbCl(2)-xAgCl where x is the AgCl concentration. Optical transmission range extends from 400 nm in the visible spectrum to 7 mu m in the infrared. Refractive index is close to 2
