    Abstract:

    We have reported the characteristics of a Z-scan for the poly(azaneylylidene-acylene) (DAZA) polymer, as nonlinear medium with a large nonlinear phase shift using continuous-wave (CW) laser beam. It has been verified that the Fresnel diffraction model is applicable for analyses of Z-scan measurements with DAZA polymer at high laser power. It was found that Z-scan curves with peak-to-valley features appear as the applied light intensity increases in the case of a large nonlinear phase shift. The Z-scan experiments were carried out using a CW laser to verify the theoretical calculations in the case of a large nonlinear phase shift model. Our results show good agreements between the experimental data and the proposed theoretical models.
