高能激光大气传输的效能与大气因素密切相关, 大气中的气体分子、气溶胶等导致了激光大气传输的衰减效应、湍流效应和热晕效应, 进而使得到达目标处的激光功率密度下降。由于实际大气环境的复杂性, 多种大气因素的耦合制约了高能激光传输机理的研究, 数学物理模型的检验存在着许多不确定性因素。采用大气因素可控的激光大气传输通道模拟器进行实际大气环境的模拟对于高能激光大气传输研究极其重要, 它不仅能够定量化探索大气各因素对激光大气传输的影响机理, 验证物理模型仿真结果的准确性并完善模型的可靠性, 还可以为激光传输效果的评估提供基础数据。文中介绍了一种可同时模拟激光大气传输湍流效、衰减和热晕等效应的实验装置的设计。

The efficiency of high-energy laser atmospheric propagation is closely related to atmospheric factors. The gas molecules and aerosols in the atmosphere cause the attenuation effect, turbulence effect and thermal blooming effect, and the laser power density at the target is reduced. Due to the complexity of the actual atmospheric environment, the coupling of various atmospheric factors constrains the research of high-energy laser propagation mechanism. There are many uncertain factors in the testing of mathematical physical models. The simulation of the actual atmospheric environment using the laser atmospheric propagation channel simulator controlled by atmospheric factors is extremely important for the study of high-energy laser atmospheric propagation. It can not only quantitatively explore the influence mechanism of atmospheric factors on laser atmospheric propagation, and verify the simulation results of physical models. Accuracy and improved model reliability also provide basic data for the evaluation of laser propagation effects. The design of an experimental device that can simultaneously simulate the laser propagation effects of turbulence, attenuation and thermal blooming is introduced.
