采用已建立的一套较完整的包括真实自适应光学位相补偿系统仿真的高能激光大气传输的数值模拟程序,对非线性热晕效应相补偿进行了计算。分析了非线性热晕效应位相补偿不稳定性的基本特征。详细讨论了自适应光学系统带宽以及变形镜驱动器间距对非线性热晕效应位相补偿的影响。

By using the four-dimensional propagation code including the model of a realistic adaptive optics system, adaptive optics phase compensation for nonlinear thermal blooming effects of the high energy laser them propagation in the atmosphere is numerical simulated. The phase compensation instability (PCI) characteristics are analysed. The influence of the bandwidth (time delaying) and the deformable mirror interactuator spacing of the adaptive optics system on the phase compensation efficiency are discussed in detail.
