ABSTRACT: This paper is focused on discussion of various experimental techniques that are used to measure non-linear coefficients of refraction and absorption in optical glasses. These techniques are usually classified as z-scan and pump-probe like methods. Measurements at different wavelengths enable to study non-linear properties of highly non-linear chalcogenide glasses close to the bandgap frequency and far from it. In addition, the recombination time of the excited states in two chalcogenide glasses is measured.
