空间碎片激光清除系统中的激光参数选择

Parameters selection of ground-based Laser in space debris cleaning system

对比分析了地基激光和天基激光清除空间碎片系统的优缺点,结果表明更适合优先发展地基激光清除系统。对比分析了连续激光与脉冲激光的优缺点,结果表明脉冲激光在空间碎片清除系统中更具优势。讨论了波长、重复频率、光束质量等因素对空间碎片清除的影响,结果表明远红外激光和近红外激光各具优缺点,空间碎片清除对重复频率的要求较低,对光束质量的要求较高。对于地基激光清除空间碎片系统中激光参数的选择提出了合理化建议。

Analyzing the advantages and disadvantages between ground -based and space -based laser in space debris cleaning ,found that it was more adaptive to develop ground-based laser .Comparing the differences of CW and pulsed lasers ,concluded that the later had more merits .Discussed the effects of wave length ,repetition rate and beam quality in cleaning space debris ,results indicated that space debris cleaning system had low requirements on repetition rate but high requirements on beam quality. And also put forward reasonable suggestions on parameters selection of ground - based lair.
