Abstract
The effect of limited operation speed of an adaptive optics system with a Shack–Hartmann wavefront sensor (WFS) on the efficiency of correction of dynamic laser beam phase distortions due to atmospheric turbulence is numerically studied. We suggest estimating the frequency bandwidth of significant turbulent distortions with a WFS, which is convenient from a practical point of view.
