| 摘 要： | 大气中的受激喇曼散射(SRS)作为强激光大气传播的非线性效应之一,在当前日益引起人们的重视和关注。本文在SRS理论的基础上,较为全面地分析和讨论了大气中的N_2的SRS及其对强激光传播的影响,计算了在几种不同波长情况下,大气中N_2的SRS增益系数、阈值强度和转换效率,同时就瞬态效应的影响进行了初步的分析和计算,得到有意义的数值结果。

| Abstract: | Based on the theory of stimulated Reman scattering (SRS), this paper discusses the SRS of N_2 in the atmosphere and its effects on high power laser beam propagation. The calculation of the gain coefficient, threshold intensity and conversion efficiency in case of several wavelengths are given. Then the e effecls of the transient SRS on the gain coefficient and threshold intensity are also discussed briefly, and the significant result is obtained. |
