摘要
采用快速傅里叶变换,研究了激光在大气传输中的热晕现象。得出了一定条件下,热晕随激光输入功率和传播距离的稳态变化规律,并计算了激光在大气中传输10km时发生热晕的功率阈值。在瞬态情况下,研究了有风和无风热晕现象。
Thermal blooming in atmospheric laser propagation is studied using Fast Fourier Transformation. Variations of steady state thermal blooming with laser power and propagation distance are introduced and power threshold is also calculated. Time-dependent thermal blooming effects with and without wind are also considered.
