Abstract

The paper presents a closed-loop adaptive optics (AO) system that uses two deformable mirrors (DMs) to compensate for both amplitude and phase fluctuation of output beam. The validation and feasibility of an AO technology using two DMs has been verified experimentally. Consequently, the quality of laser beam in the near field is improved and the far field image is close to diffraction limit in the experiment. The Strehl ratio (SR) of far-field image increases from 0.837 using conventional AO technology to 0.952 using the two DMs AO technology.
