摘要: We prepared AgxAs0.4Se0.6100-x chalcogenide glasses by a melt-quenching method and measured their linear and nonlinear optical properties to evaluate potential applications all-optical ultrafast switching devices. Their nonlinear refraction absorption were measured by the Z-scan at 1.05 µm. The addition of Ag As2Se3 glass led an increase in refractive index without introducing an increase coefficient. glass with content of x=20 at.% revealed high nonlinearity ranging from 2000 27,000 times that fused silica, depending on incident intensity.
