A model for 10.6 µm high energy laser beam interaction with a uniform, monodisperse cloud of water droplets is developed. The model includes droplet and vapor heating as well as droplet shattering in the "fast regime" as defined in Appl. Opt.28, 3671 (1989)APOPAI0003-693510.1364/AO.28.003671. The cloud dynamics feed back on the laser via changes in the complex refractive index. In one space dimension, the model is solved exactly, including an explicit formula for the front of the cleared channel. Numerical simulations are conducted for the axisymmetric three-dimensional case. Model predictions and limitations are discussed.
建立了一个10.6微米高能激光束与均匀单分散水滴云相互作用的模型。该模型包括液滴和蒸汽加热，以及如《应用光学》28, 3671 (1989) [APOPAI0003 - 693510.1364/AO.28.003671]中所定义的“快速模式”下的液滴破碎。云团动力学通过复折射率的变化反馈到激光上。在一维空间中，该模型得到了精确求解，包括清除通道前端的显式公式。对轴对称三维情况进行了数值模拟。讨论了模型的预测和局限性。
