The reflective spectra of two glass systems of Na2O-ZnO-GeO2-SiO2-PbO(Sb2O3) were measured to study the effects of PbO and Sb2O3 on properties in SiO2-based glasses. The infrared reflective coefficients and anomalous dispersion regions change with the content of PbO and Sb2O3 respectively, furthermore the refractive indices (nr) of glasses are 0. 81 and 0. 84 at the wavelength of CO2 laser (940cm-1). The glasses of two systems can be used as the cladding materials of hollow waveguides for transmitting CO2 laser.展开更多
