TeO2-based glasses have been attractive because of their high refractive index and third-order nonlinear optical properties. In general, long melting time is required to obtain the homogeneous glass, but it also leads to enhanced interaction between the crucible and the glass melt. In this study, 20Ag2O–80TeO2 nonlinear optical glasses were fabricated by a melt-quenching method using an alumina or platinum crucible for various melting times. And their thermal characteristics, final glass-compositions, glass structures and linear/nonlinear optical properties were evaluated in order to investigate the influences of the incorporation of Al2O3 in 20Ag2O–80TeO2 glass on third-order nonlinear optical susceptibilities.
