It was found that the optical reflection greatly depends on the type of the nonlinear crystal and dichroic material used, the type of the refractive index (ordinary or extra-ordinary), direction of propagation inside the nonlinear material, optical thickness and the number of anti-reflection coating layer used. The calculated refracted index was found to be 2.232 for the 1064nm wavelength for LINBO3 crystal and 1.655 for 1064nm for the BBO crystal. The results show that the reflectivity reaches the best value when the refractive index difference between the anti-reflection coating layers is small, and increasing the number of such layer. The calculated phase-match angle is equal to 13.75177°.
