Adaptive optics technology was widely used in large-scale ground-based optical telescope to correct the wavefront distortion caused by atmospheric disturbance, make the telescope reach the resolution near diffraction limit, and realize the clear imag-ing of the observed object. As the beacon source of adaptive optical correction, laser sodium guide star was one of the core technologies of adaptive optical telescope. The latest research progress of the new sodium beacon laser was demonstrated, include the 589nm optical pumped vertical external cavity surface emitting semiconductor sodium guide star laser and the all solid-state laser with Dy3+-doped crystal as gain medium, which can directly emit 589nm laser. Due to their advantages of small size, high efficiency, high reliability, low cost and easy maintenance, these schemes are considered as the possible development direction of the new generation of sodium guide star lasers.
