Abstract

Nonresonant photoinduced birefringence of an acceptor-donor azo dye doped in polymethyl methacrylate film was studied by degenerate four-wave mixing and Z-scan methods with a He-Ne laser. The sample has appreciable large third-order nonlinear susceptibility and polarization sensitivity. The nonlinear mechanism of the material originates from photoinduced birefringence of polar azo molecule.
