Accurate Determination of Nonlinear Refractive Index for Some Binary Glass Systems

ElSayed Moustafa

Abstract

Problem statement: This study investigates the relation between the nonlinear optical susceptibility (χ(3)) and the ratio (α1o-2), then the nonlinear index determination for some binary glass systems. Recently suitable relationship between the oxidation polarizability and the nonlinear optical properties was established for simple oxides glasses. So in this study more attention and investigation is paid to the trend of that relation quantitatively as possible. Approach: The idea of the present research is how to obtain the non linear refractive index as function of ratio (α1o-2), as we know the cation polarizability αl can be determined easy and αo-2 also can be obtained according the energy gap or the real refractive index. Consequently a proposed scale has been established between the nonlinear optical susceptibility (χ(3)) and the ratio (α1o-2) for some binary glass systems. Results: A comparison between our obtained results and the empirical method of Boling shows that there is a good agreement between them. Conclusion: The advantages of the suggested method fix on the expectation of the value (χ(3)) without the complex and sensitivity experimental set-up.
