为了研究高能激光对cm级空间碎片的清除过程，通过分析空间碎片在激光作用下的变轨过程，建立了物理模型；数值模拟了空间碎片在激光作用下烧蚀反喷进入大气层烧毁的过程。结果表明:空间碎片运行速度与速度增量之间的夹角大于90°，才能满足进入大气层烧毁的条件；cm级空间碎片的清除，需要105 W以上的高功率激光器。

The orbital change of space debris using laser irradiation was analyzed to study the laser removal processes of centimeter-scale space debris. A physical model was build up, and the space debris re-entering and burnout processes were studied numerically. The results indicate that in order to remove the debris of centimeter scale, the included angle between the direction of velocity and the velocity increment must be larger than 90°, and the laser power should be up to 100 kW.
