This paper gives an overview of the use of a wave optics computer code to model the propagation of high power CO(2) laser beams in the atmosphere. The nonlinear effects of atmospheric heating and kinetic cooling phenomena are included in the analysis. Only steady-state, nonturbulent cases are studied. Thermal conduction and free convection are assumed negligible compared to other effects included in the calculation. Results showing the important effect of water vapor concentration on beam quality are given. Beam slewing is also studied. Comparison is made with geometrical optics results, and good agreement is found with laboratory experiments that simulate atmospheric propagation.
本文概述了利用波动光学计算机代码对高功率CO₂激光束在大气中的传播进行建模的情况。分析中考虑了大气加热和动力学冷却现象的非线性效应。仅研究稳态、非湍流情况。与计算中包含的其他效应相比，假定热传导和自由对流可忽略不计。给出了表明水汽浓度对光束质量有重要影响的结果。还对光束摆动进行了研究。与几何光学结果进行了比较，并且与模拟大气传播的实验室实验结果吻合良好。
