Abstract:

An analysis of current investigations of multichannel laser systems is presented in the paper. Sources of aberrations in such systems are described along with the methods of their active and passive compensation. Numeric investigation of multimode beam propagation has been carried out. Influence was studied of random phase shifts and atmospheric turbulence on the beam parameters registered in the plane of observations. Application of the multidither algorithm for correction of these distortions was analyzed, and the obtained results and possibility of transferring energy with the use of the system are discussed.
