The invention relates to the technical field of adaptive optical systems, in particular to a laser sodium guide satellite full emission link compensation system. The laser sodium guide satellite fullemission link compensation system comprises a first laser beam expanding system, a color selective mirror, a deformation mirror, a spectroscope, and a beam combining and beam expanding system which are arranged successively along an emission path, a second laser beam expanding system, a first beam shrinking device, a first wave front detector, a wave front detection and control system, and a reflecting mirror, and a calibration light source, wherein the first laser beam expanding system, the color selective mirror, the deformation mirror, the spectroscope, and the beam combining and beam expanding system are arranged in sequence along an emission path, the second laser beam expanding system is located in the incident direction of the beam combining and beam expanding system, the first beamshrinking device and the first wave front detector arranged successively are located on the reflection direction of the spectroscope, the wave front detection and control system is located on the reflection direction of the spectroscope, and the reflecting mirror and the calibration light source are arranged between the deformation mirror and the spectroscope. According to the laser sodium guidesatellite full emission link compensation system, distortions of sodium laser, abeam expanding transmission light path, and atmosphere turbulences are compensated by using a single deformable mirror,a double wave front detector and another laser with a different wavelength from the sodium laser to ensure that the sodium laser has good distribution characteristics and sodium guide satellite lightspot qualities when the sodium laser reaches a sodium layer.
