Abstract

This paper describes the design and technical features of the Rayleigh laser guide star (LGS) system as a reference source of an adaptive optical system developed for use on the Zeiss-2000 telescope of the Terskol Peak Astronomical Observatory (coordinates 43°16’34”, 42°29’57”). Experiments were performed on the Zeiss-2000 telescope to test the developed system. As a result, a signal was received from the LGS sufficient for the operation of the wavefront sensor. The presented numerical estimates of the effectiveness of adaptive correction from the Rayleigh LGS show that in the future, the use of an adaptive optical system on this telescope will significantly improve the quality of the generated image by increasing the Strehl ratio by at least ten times.
