【摘要】 本文从动力学理论出发,导出了在红外聚焦脉冲激光场中分子离解速率和同位素浓缩系数对激光脉冲能量、透镜焦距、激光脉冲辐照次数等参数的关系式。理论公式与SF₆的有关实验结果作了比较,符合得很好。此外,通过理论与实验的比较,提供了进一步研究离解机理的有益信息。更多还原

【Abstract】 In this work, the expressions of molecular dissociation rate and isotope enrichment coefficient in an strong IR field, as the functions of the laser energy per pulse, the focal length of lens, the number of laser pulses, and etc., were derived by using the kinetic theory. The theoretical expression of isotope enrichment coefficient was compared with the experimental results for SF6, and good agreement was found. In addition, the theoretical expressions compared with experiments would provide some useful informations of the molecular dissociation in the strong IR field.更多还原
