Atmospheric turbulence has significant impact on the laser beam propagating through atmosphere over long distances. Application of adaptive correction is necessary to control spreading and wandering of the laser beam in wireless power transfer (WPT) system. In this paper we present system and techniques for laser WPT with adaptive correction. Control of position, wavefront tip and tilt is used for adaptive beam shaping and maximizing receiver efficiency. We describe results of a set of experiments performed over a 1.5 km path. The results show that overall efficiency can be increased over than 5% by using of presented adaptive correction technique.
