    High-power narrow-linewidth 589 nm lasers are able to excite the sodium layer with 10 km thick. ness at the altitude of 90 km and emit the backward scattering. Sodium guide star generated by 589 nm laser is con. sidered as a bright beacon for ground-based optical telescope adaptive optical system. The basic principles of sodi.um atomic transitions, the approaches to improving the sodium beacon brightness, the applications of sodium lasersand the evolution of 589 nm sodium laser systems are presented.
