Abstract

In report we review aspects related to the implementation of laser guide star (LGS) in an adaptive optics (AO) system. As soon as lasers were proposed to create guide star for adaptive optics, it was realized that the LGS could not be used to measure tilt. In report the analysis of the possibility of tilt-measurement in the framework of using a LGS are discussed. Results of analytical calculations where assumptions made earlier remove are presented. We suggested the use the algorithm of 'optimal' correction for determination correction the wavefront aberration of the science object by means of the measured wavefront LGS. The analytical and numerical calculations are presented. For numerical calculation we used set the various model of turbulence profile. The significant increases in efficiency of phase correction based on this algorithm are achieved.
