This paper presents some experimental results of investigations into the wave front (WF) distortion and possibility of wave front reconstruction at wave front inversion of a XeCl-laser beam. The divergence of a beam with the diameter of 150 mm at propagation to 25 m distance increases up to 20 Θд due to the air turbulence aberration. The WF inversion of a beam distorted due to aberrations of an optical element (Θ≤15Θд), may result in their complete compensation. If the aberrations are caused mainly by the air turbulence, then the accuracy of the wave front inversion decreases.
