摘要

Abstract

In this paper, we describe the design and technical features of the Rayleigh laser guide star (LGS) system as a reference source of the adaptive optics system (AOS) intended for use at the Zeiss-2000 telescope of the Terskol Peak Astronomical Observatory (coordinates \(43\overset{\circ}{.}27631\) N, \(42\overset{\circ}{.}49939\) E) located at an altitude of 3150 m above sea level. Experimental testing of the Rayleigh LGS system at the Zeiss-2000 telescope was carried out. The presented numerical estimates of the correlation radius \(r_{0}\) show that in the future, the use of an AOS with a Rayleigh LGS at this telescope will improve the quality of the formed image by an order of magnitude.
