As generally accepted, TeO₂-based glasses have been attractive materials because of their wide optical window, high refractive index and third-order nonlinear optical properties. In this study, we fabricated 20Ag₂O-80TeO₂ nonlinear optical glasses by a melt-quenching method with alumina and platinum crucible, and evaluated glass structures and linear / nonlinear optical properties. The measurement of third nonlinear optical susceptibility Reχ⁽³⁾ was conducted by a Z-scan method and the highest Reχ⁽³⁾ was 1.19×10^-12 esu (20Ag₂O-80TeO₂-2.5Al₂O₃ using Pt crucible) which is comparative to that of α-TeO₂ single crystal.
