用于空间碎片清除的高功率激光器（英文）

虽然人类的太空活动已经考虑了尽量减少空间碎片的措施,但近地轨道碎片的数量仍呈指数增长,特别是中小型碎片的现有数量已对在轨卫星构成了实质性的威胁。作为具有较高期待的消除碎片办法,用地基DF激光器和空基Nd∶YAG激光器消除碎片的方案令人关注,它们可以以低成本和非破坏性的方式清除空间轨道的危险碎片。本文介绍了使用平均功率为100 kW的高功率、高重复频率P-P Nd∶YAG激光器和平均功率约为1.5 MW的DF激光器来保护在轨飞行器和清除直径为1～10 cm空间轨道危险碎片涉及的相关工作。

High power lasers for space debris elimination

A number of debris in low earth orbit is exponentially growing although future debris release and mitigation measures have been considered in human space activities. Especially, an already existing popula- tion of small and medium debris is a concrete threat to operational satellites. Ground-based DF laser and space-based Nd： YAG laser solutions appear as a highly promising answer, which can remove hazardous debris around the selected space assets at low expenses and in a non-destructive way. This paper introduces a re- search on the Space Vehicle （CV） protection and the orbit clearing from dangerous Elements of Space Debris （ESD） with diameters from 1 to 10 cm by means of a high-power and high repetition rate P-P Nd： YAG laser with an average power of 100 kW and a DF-laser with an average power about 1.5 MW.
