Paper Abstract

A deformable annular flat mirror was developed for performing adaptive corrections of low temporal frequency aberrations in cylindrical lasers. Construction of the mirror is described, including the aluminum. faceplate, 4ifferential ballscrew actuators, and servomotor drivers. The annular deformable mirror aperture, having two free edges, presents unique problems for optical finishing due to edge roll-off as well as actuator print-through. These problems were successfully overcome by diamond turning the deformable mirror rather than employing conventional grinding and polishing techniques. It is believed that this is the first successful demonstration of diamond. turning a deformable mirror structure to optical tolerances.
