Abstract

Method for measuring nonlinear refractive index (n₂) of optical materials is presented. It is based on the analysis of large scale beam distortions caused by the nonlinear aberrational lens induced by power radiation in the medium under study. Absolute n₂-values for new Russian laser phosphate glass KGSS 0180/35 (n₂ ≈ 1.2•10^-13 CGSE units) and widely used glasses GLS 22 (n₂ ≈ 1.9•10^-13 CGSE units) and K8 (n₂ ≈ 1.4•10^-13 CGSE units) were obtained with this method for laser pulse duration of 4 ns. Also, evaluation of nonlinear phase delay induced in the laser beam that has passed through the glass samples under study for a longer pulse duration of -up to 25 ns has been performed.
