Abstract
The effect of limited operating speed of the adaptive optics system with a Shack-Hartmann wavefront sensor (WFS) on the correction efficiency of dynamical laser beam phase distortions caused by the atmospheric turbulence is numerically studied. Estimation of frequency bandwidth of essential turbulent distortions with the help of WFS has been proposed, which is convenient from a practical point of view.
