Characterization of thin ZnO film by optical second harmonic generation: experiment and theory

Thin polycrystalline zinc oxide film deposed on glass substrate have been investigated by optical second harmonic generation (SHG). The intensity of SHG in dependence of rotation angle of fundamental beam polarization for several incident angles has been measured. Developed theoretical model taking into account multiple reflections of light into the sample allows us to reveal a set of effective characteristics of film.
