This paper puts forward an adaptive optics (AO) mounting method of large aperture KDP frequency doubler used in high power solid state lasers. Integrated optomechanical theory is proposed and applied to verify the mechanical and optical performances of this AO method particularly. According to the thin plate theory and nonlinear optics theory, optomechanical model is developed. Then, the finite element method is employed to establish the numerical model and simulate the distortion process of the crystal plates under various boundary conditions. The results indicate that this AO method could correct the deformed surface and modify the phase matching condition significantly, which means the second harmonic generation (SHG) efficiency will be improved as well.
