Connection Between Propulsive Performance of Repetitive Pulse Laser Propulsive Working Medium and Inputting Laser Parameter

重复脉冲激光推进过程中，入射激光的能量、波长、脉宽、光斑大小、重复频率等参数变化对激光推进工质推进性能有着直接影响。在对国内外实验数据分析、研究的基础上，总结了10．6μm、1．06μm 2种波长激光与工质相互作用的实验研究成果，通过对实验数据进行科学分析，得出输入激光参数与工质推进性能的关系，并给出约定条件下优化激光输入参数。

In the course of repetitive pulse laser propulsion, inputting laser parameter, including energy, wavelength, pulse duration, facula size and repetitive pulses, and so on, have direct influence on the propulsive performance of laser propulsive working medium. Based on a thoroughly research on experimental data of the home and foreign literatures, progeny of experimental research for interaction between laser and working medium is summarized, with laser wavelength of 10. 6μm andl. 06μm . Through analyzing experimental law, connection between the propulsive performance of laser propulsive working medium and inputting laser parameter is found. The optimizing laser parameter is given under special condition.
