. Glass ceramic composite materials based on germanotellurite system doped with silver oxide has been thermally poled to investigate the possibility of combining nonlinear optical properties of ceramic components and the modified structural surface layer of glass component. Nonlinear optical properties of three types of samples: thermally poled doped silver oxide doped germanotellurite glass materials, ceramic glass composite and thermally poled glass ceramics composite of the same system are investigated based on Second Harmonic Generation in the same experimental conditions. The results demonstrate the ability to combine two methods to improve the special nonlinear optical properties of this materials.
