Abstract: With Z-scan technique, we have measured nonlinear optical coefficient of organic thin films doped with push-pull azobenzene compounds, Experimental analysis shows that nonlinear refractive index is caused by π-electrons effect.

Key words: nonlinear refractive index, azobenzene compounds, Z-scan
