Abstract

An optical surface with convex parabolic shape over a large area has been created using a 12.7-mm-diameter annular pusher to deform a flat 25.4-mm-diameter mirror. The deformable mirror assembly has been modeled using finite element analysis software as well as analytical solutions. The measured parabolic surface deformation shows good agreement with those models. Mirror performance was studied using a Shack–Hartman wavefront sensor and the mirror has been applied to compensate thermal lensing in a Nd:YAG rod amplifier.
