Abstract

KDP frequency converters are the important components applied in the final optics assembly for Inertial Confinement Fusion device. And the efficiency of second harmonic generation is much affected by phase matching error, which is induced by surface distortion. In this paper, focusing on the surface distortion under the specific mounting process of KDP frequency converters, we proposed an effective prediction method based on modified mechanical model to accurately predict the surface distortion during assembly. Using numerical simulation, we analyze the key elements that influence the surface distortion so as to adjust the mounting process according to the results. Results and findings in this article are meaningful for improving mounting-induced surface distortion of KDP frequency converters. Moreover, the mechanical model and prediction method presented will offer more efficient and reliable technical proposal for next generation ICF facility
