Nonlinear optical properties of an azo dye attached polymer

Abstract

Copolymers of azo dye substituted acrylic monomer and methylmethacrylate are synthesized and their third-order nonlinear optical susceptibility χ(3) is evaluated using the third harmonic generation Maker fringe method. The χ(3) is 1.26×10−12 esu at 25.9 mol % azo dye monomer content in the copolymer. It is also shown that there is a linear relationship between χ(3) and the monomer content.
