Abstract: Theoretical investigation of frequency conversion in ZnO films laid over glass substrates with account for phase effects has been developed. For this the constant-intensity approximation of fundamental radiation is applied. The numerical calculation of the efficacy obtained in constantintensity approximation confirms the following that because of dispersion of the second order nonlinear optical coefficients the generated signal decreases for an increasing fundamental wavelength. Furthermore, the zinc oxide films generate stronger second harmonic signal because of the larger interaction length of the nonlinear medium. Method of analysis of second harmonic generation in zinc oxide, grown on glass substrate used in the present work, may be involved for research of other films.
