Abstract: Based on the introduction to theresearch status and trend of international space-based laser debris removal technology, the existing problems of space-based laser debris removal technology are systematically analyzed. 
In view of the existing problems, the work and research progress of the Beijing Institute of Spacecraft Environment Engineering in this field are introduced from several aspects, such as dynamic behavior of laser-driven debris, orbit transfer model, ground simulation system, space-based removal system scheme and target selection strategy. The main research methods include laser-driven micro-impulse measurement experiment, surface triangulation three-dimensional reconstruction calculation method based on laser-material interaction theory, simulation calculation based on orbital dynamics, etc. It also looks forward to the future research direction in the field of this technology.
