In this paper analysis of constant-intensity approximation of nonlinear interaction of the second-harmonic generation in ZnO/PMMA nanocomposite films for different concentrations of ZnO was carried out with regard to the losses and phase changes of all the interacting waves. The investigated samples were manufactured on the basis of ZnO nanoparticles embedded into polyvinylchloride polymeric matrix (PMMA) by the method of electrochemical deposition. The main goal of work is the exploration of the ZnO morphology and parameters of the second order susceptibilities. It is verified that the surface effects in ZnO/PMMA structures will give a larger contribution than the volume effects. The factors restricting the efficiency of the process of frequency conversion have been analyzed.
