Abstract: Theoretical investigation of frequency transformation for the case of pure ZnO films, ZnO: Ag (1.6 at.%) and ZnO: Cu (4.7 at.%) enables increasing conversion efficiency while taking phase effects into consideration. We will use the constant-intensity approximation of fundamental radiation. This analytical method also allows to approximately measure the maximum of second–harmonic intensity for the case of ZnO films with silver and copper impurities. We will analyze the parameters that restrict the efficiency of frequency conversion. We can calculate the coherent length of crystal converter at given pump intensity. These methods of investigation for second-harmonic generation in pure and doped ZnO films can be useful in the research area of other film.
