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。 A four-dimensional simulation program of high-energy laser atmospheric transmission was used to analyze the flare expansion caused by turbulent thermal-halo interaction when the high-energy laser was transmitted in the atmosphere. Under different turbulence effects, the flare expansion of 63.2% energy radius of the focal plane caused by the thermal halo effect and the calibration of the average power density in different spot radius are obtained. According to this calibration relationship, the effect of high-energy laser transmission in the atmosphere can be rapidly predicted and effectively evaluated.
