摘要：

Before using the deformable mirror (DM) for wavefront beam shaping, it is necessary to correct its surface profile to reduce the high-order aberrations, because the DM surface profile is different from the original set plane. In this paper, we demonstrate a simple method to correct the DM surface profile. The method is verified experimentally by using He-Ne laser. Results show that the DM surface profile is corrected to be near flat-topped by using the method. The output peak-to valley value changes from 2.38 lambda to 0.21 lambda of the He-Ne laser and the RMS value changes from 0.49 lambda to 0.04 lambda after correcting the DM surface.
