摘　　要：本文综述了强激光束在大气中的自聚焦效应及其与大气击穿、受激喇曼散射、热晕的关系,并就其对激光大气传播的影响和对大型实用激光系统设计的要求进行了初步的分析和讨论。Self-focusing of a high pawer laser beam in the atmosphere and its relations with air-breakdown, Stimulated Raman Scattering (SRS) and thermal blooming are reviewed. The effects on the propagation through the atmosphere and the requests on designing future large practical laser systems are analysed and discussed preliminarily.
