| Abstract | ||
| We present experimental and a theoretical study on the Z-scan characteristics of the nonlinear optical thin films with simultaneous. Two-photon absorption (TPA) employing SHG pulsed Nd:YAG laser with pumping energy 400mJ. The ZnO thin films prepared by Spray pyrolysis, with different concentrations. The absorption ZnO thin films are a two-photon absorption process is confirmed by the peak- to- valley distance. In transmittances curve is around (4.306Zo) for closed aperture and (2.153Zo) for open aperture | ||
