Abstract
The laser guide star (hereinafter referred as LGS) is created by a physical process in the Earth atmosphere. Consequently it is located at a finite distance from the observer, which results in the so-called cone effect, or focus anisoplanatism. The volume of the atmosphere from the LGS to the telescope mirror is a cone, whereas it is a cylinder from any astrophysical source because it is located almost at infinity. This difference causes errors in the measurement of the phase disturbances of the incoming wavefronts [1].
