AB - The numerical simulation has been carried out concerning the determination of needed number of adaptive mirror’s actuators for the correction of phase distortions accumulated by the laser beam under its propagation through an airway. For this purpose, a set of wavefronts of the laser radiation passed through the airway has been registered by a Shack-Hartmann wavefront sensor. The stacked actuators’ response functions of 107- and 203-element adaptive mirrors have been experimentally determined as well. The dynamic range of adaptive mirrors’ actuators has been considered in the calculations. It is established that the 203-element adaptive mirror is not suitable for correction of the registered aberrations due to the limited dynamic range. Meanwhile by means of 107-element adaptive mirror it is possible to obtain a corrected laser beam with the Strehl ratio St=0.65.
