The physical and optical properties of glasses having a composition 59TeO2 x SrO (40-x) B2O3 1V2O5, where (x = 10, 20, 30) have been studied. It was found that the values of density and molar volume increase by increasing SrO content for all the studied samples. Also, it was found that the values of the optical energy gap decrease while as the values of the refractive index increase by increasing SrO content. The optical basicity of the glasses and the polarizability of oxide ions have been calculated. It has been found that all the studied glasses become more polarized and more basic by increasing SrO content. Also, all the studied samples show insulating behavior. Finally, all the prepared samples have higher values of third order nonlinear susceptibility (6.92-8.34) x10-13 esu, this means that all the studied samples are promising materials for nonlinear optical devices
