Abstract
With the aim to decrease the distortion and the stress as well as to increase the Second Harmonic Generation (SHG) efficiency, a novel mounting configuration with plug function of the optics was proposed, a comprehensive model of the mechanics and the optics was built, and the influences of the frame stiffness on the distortion and the stress as well as on the SHG efficiency were investigated. The distortion and the stress were calculated by using a Finite Element Method (FEM) and their changing trends with the varying frame stiffness were pointed out. Furthermore, the phase mismatches induced by the distortion and the stress were calculated, and the SHG efficiency considering the phase mismatch was studied. The results revealed the availability of the mounting configuration and the feasibility of increasing the SHG efficiency by improving the frame stiffness.
