选取多种典型激光传输条件下的计算参量,对平台光束聚焦大气传输湍流热晕相互作用引起的光束扩展进行了数值分析.热畸变的产生是在快速变化的湍流扩束作用之后,在此假定的基础上,建立了描述聚焦光束大气传输光束扩展与大气传输特征物理参量的定标关系.在了解激光发射系统的特征参量和大气传输效应的特征参量之后,即可由定标关系迅速判断激光大气传输的效果,从而为激光工程系统的参量优化设计及其应用效能评估提供依据.
The numerical calculation of the beam expansion caused by the turbulent thermal-halo interaction of the platform focused on the atmospheric turbulence is carried out by taking into account the calculated parameters under a variety of typical laser transmission conditions. The thermal distortion is generated after the rapidly changing turbulent expansion effect. , A calibration relationship describing the physical parameters of the atmospheric transmission beam expansion and the atmospheric transmission of the focused beam is established.After knowing the characteristic parameters of the laser emission system and the characteristic parameters of the atmospheric transmission effect, the laser atmosphere Transmission effect, which will provide the basis for the optimization design of laser engineering system parameters and the evaluation of its application efficiency.
