Abstract

Zinc oxide thin films grown by modified spray pyrolysis technique on MgO substrates have been investigated by optical second harmonic generation (SHG). ZnO films were grown at a substrate temperatures from 300 to 600 degree(s)C. It was found to influence the structure of the films. Dependence of second harmonic intensity on angle of fundamental beam incidence revealed both a- and c-axis oriented growths in ZnO/MgO systems. Effective nonlinear optical susceptibility coefficients as high as 0.5 pm/V have been obtained from as-grown films. SHG polarization dependencies was carried out to show in-plane anisotropy in these films.
