Abstract

A multi-actuator deformable mirror and control system is described that will cancel laser wavefront phase errors caused by the quasi-static aberrations occurring in large aperture metal mirror optics. The design of the differential ball screw driven mirror, its characterization and system performance are detailed. By using a sequential dither focus irradiance sensing/optimization algorithm, the system is shown to be able to correct wavefront aberrations of up to 4 waves p-p at 10.6 µm.
