Influence of spatial wavefront characteristics of laser radiation on quality intracavity modal correction

The laser systems supplied by an adaptive optical system allow obtaining output beam with high quality spatial-power characteristics. The efficiency of functioning of adaptive optical system phase conjugation with modal correcting by the bimorph deformable mirror of the resonator was investigated. The form of a mirror surface was modeled by Zernic polynom, and wavefront was modeled by the spline-interpolation of the limited set of random numbers. In the decision of the task of formation of operation action on a deformed mirror various methods of optimization were used. The influence of a standard deviation and relative entropy both of phases and angles of the slopes of the wavefront on quality of correction was examined. The quality of correction was estimated on static and dynamic errors of wavefront reconstruction. Moreover connection among spatial characteristics of a radiation beam was estimated
