Abstract
A theoretical model was proposed to simulate the broadband second harmonic generation (SHG) based on random quasiphase matching (RQPM) by Fourier transform mothed. A broadband SHG experiment system was built which could obtain the distribution of the SHG signal over a whole ZnSe sample. Both the simulated and experimental results demonstrated that the main feature of RQPM is the linear dependency of the SHG intensity with sample thickness.
