Abstract

A novel technique, which employs a modified Twyman-Green interferometer, is used to measure the nonlinear index of a CdS_0.9Se _0.1-doped glass at different wavelengths in the vicinity of the band gap at room temperature. The measured n₂ values for the doped glass are compared with calculated values obtained by Kramers-Kronig transformation of the measured Δα(λ)=α(I₁,λ)- α(I₂,λ). A good agreement is achieved between the measured nonlinear dispersion and that obtained through the Kramers-Kronig relations.
