Novel fluorotellurite glasses with composition 70TeO2·5MxOy·10P2O5·10ZnO·5PbF2 (mol %) containing 600 ppm Er2O3, where MxOy = (MgO, PbO, Bi2O3, Nb2O5, TiO2, BaO, WO3, SrO, CdO) have been prepared using the conventional melt-quenching method. Studies of the nonlinear optical refractive index and photoinduced piezooptics were carried out. The Mid-Infrared spectroscopy, optical transmission, photoluminescence and photoinduced changes of diagonal piezooptics and nonlinear optics refractive indices coefficient measurements were applied to determine the appropriate glass modifier to achieve the desirable optical properties and high performance. The glasses may be useful for operation by high-intensity laser pulses.
