Author Affiliations +
A 19-element serial hill-climbing adaptive optical system is introduced. By using a 19-element deformable mirror, a detector for sharpness of the focal spot and a dither control system, it can correct static and slowly varying dynamic wavefront errors. The hill-climbing control algorithm, experimental setup and correction effect are reported. Experimental result shows that this system can be used in large laser engineering system for wavefront error compensation and far-field sharpness improvement.
