【Abstract】 Chalcogenide glass with a new composition of 70GeS₂-15Ga₂S₃-15Ag₂S had been prepared by melt-quenching technique.Glass-ceramics purely containing the excellent nonlinear optical crystal AgGaGeS₄ were fabricated successfully,which is suitable for the application in mid-IR spectral region according to the linear optical properties and Vickers microhardness studies.A clear green light,corresponding to the SH wave（532 nm）,was observed coming from the AgGaGeS₄ crystallized glasses,demonstrating that the glass-ceramics have a function of wavelength conversion based on a second-order optical nonlinearity.These excellent properties of 70GeS₂-15Ga₂S₃-15Ag₂S glass-ceramics make them potentially applied in the optoelectronic field,such as nonlinear optical modulator.【更多还原
