Effect of clamps on surface profiles of harmonic generation KDP crystals

Considering the deformations of surface profiles of the KDP crystals with large dimension and low thickness under different clamps and departure angles from the horizontal plane in inertial confined fusion(ICF) systems, which influenced by clamps and departure angles, a finite element analysis model for the KDP crystals with large dimension and low thickness under different clamps and departure angles has been built and the boundary condition determination has been presented. For the case of departure angles from the horizontal plane of 30°and 90°, respectively, the deformations of the surface profiles under different clamps, such as full periphery simple supported and point force on the front, full periphery clamped and compliant strip on the front, full periphery simple supported and p
