Abstract: Laser ablation micro propulsion technology is one of the space micro propulsion technologies. It is a kind of electric propulsion technology based on the principle of laser propulsion. It can be used for micro nanosatellite attitude and orbit control. In this paper, the development of laser ablation micro propulsion technology is reviewed. The basic theory is briefly described. The research status is discussed. Various types of micro thrusters are compared and analyzed. Combined with the characteristics of laser ablation micro propulsion technology, the development trend is analyzed, and suggestions are given for reference.

Key words: laser ablation, micro propulsion, micro nanosatellite, propulsion performance
