An analysis, using a single-phase-sheet model, of the effect of an oscillating thermally bloomed atmosphere on a high-power laser beam is presented. The oscillations are caused by a small modulation of the wave front of the beam at the transmitter. The primary contention made here is that the time-dependent blooming is not an oscillating version of its static counterpart; rather, new gratinglike effects are introduced by the interaction of the crosswind and the dithered high-power beam. The resulting temporal variations of the target-plane irradiance at the position of its static bloomed peak are examined and implications for slow dither are discussed.
本文给出了一个使用单相片模型对振荡热晕大气对高功率激光束影响的分析。振荡是由光束在发射端波前的小幅调制引起的。这里的主要观点是，随时间变化的热晕不是其静态对应物的振荡形式；相反，侧风与抖动的高功率光束相互作用引入了新的类似光栅的效应。研究了在静态热晕峰值位置处目标平面辐照度的时间变化，并讨论了慢抖动的影响。
