摘　　要：利用高能激光大气传输四维仿真程序,对高能激光在大气中传输时湍流热晕相互作用引起的光斑扩展进行了数值分析。得到了在不同湍流效应情况下,由热晕效应引起的焦平面上63.2%环围能量半径的光斑扩展规律以及不同光斑半径内的平均功率密度定标关系式。根据此定标关系,能够对高能激光在大气中传输的效果做出快速的预测和有效的评估。The scaling laws of high energy laser propagation through atmosphere are numerically analyzed by the four-dimension simulation program of high energy laser in atmosphere. The scaling relations of the 63.2 % encircled energy beam radius spreading and the average energy intensity in the different encircled energy radius are obtained in the focal plane. The scaling relations are applicable to different atmospheric turbulence effects. Based on the relations, the atmospheric propagation effects of high energy laser can be predicted and estimated effectively.
