针对序列长脉冲激光,提出了衡量序列长脉冲激光热晕效应强度的热畸变参数,建立了序列长脉冲激光热晕效应的数值仿真模型,并进行了实验验证。对比分析后发现实验结果与仿真结果在光斑形态和大小方面具有较好的一致性,从而验证了序列长脉冲激光热晕效应的数学物理模型及仿真算法的可靠性。在此基础上,通过改变大气参数及发射系统参数进行大量的数值仿真,得出由序列长脉冲激光热晕效应引起的光斑扩展与热畸变参数的定量关系,即序列长脉冲激光热晕效应的定标规律。 Aiming at the long pulse laser, a thermal distortion parameter to measure the thermal halo intensity of the long pulse laser was proposed. The numerical simulation model of the thermal halo effect of the long pulse laser was established and verified by experiments. After comparison and analysis, it is found that the experimental results and the simulation results have good consistency in spot shape and size, which verifies the mathematic and physical models of the thermal halo effect and the reliability of the simulation algorithm. Based on this, a large number of numerical simulations are carried out by changing atmospheric parameters and emission system parameters, and the quantitative relationship between flare expansion and thermal distortion caused by the long-wavelength laser thermal halo effect is obtained. That is, the long-pulse laser thermal halo effect Calibration rules.
