Highly nonlinear tellurite glasses for mid-IR applications

Tellurium dioxide based glasses with a low hydroxyl groups concentration were synthesized in an atmosphere of dried oxygen from initial high purity oxides. Large high-quality optical elements were manufactured and investigated from the point of view of nonlinear propagation of ultrashort pulses in the mid-IR range. Optical homogeneity, thermophysical, optical, including nonlinear properties were studied.
