Abstract- In this experimental work we measure and compare third order nonlinear diffraction for two different thickness of Dimethylaminoazobenzene doped PMMA .z scan experiment was performed using Nd:Yag laser at 532 nm with the power output of 40 mw. The experimental results for close aperture show that the Dimethylaminoazobenzene doped PMMA films exhibits positive refractive index, and with thickness diminution refraction index decrease, this is due to the decreasing of the nonlinear phase shift in the samples.
Keywords: Defocusing, Dimethylaminoazobenzene doped PMMA, thin film, z-scan technique.
