为了分析组束激光的战术应用前景,对强激光大气传输的远场光束亮度进行了理论分析和数值模拟。结果表明:10kW量级的强激光有效作用距离不超过10km,需要对发射系统孔径和光束质量进行严格的控制;激光器承载平台的抖动幅度是影响远场光束功率密度的主要因素,在抖动幅度很小或者可以忽略的条件下,湍流和热晕对远场光束起着近乎相同的作用。
In order to analyze the tactical application prospect of laser beam, theoretical analysis and numerical simulation of far-field laser beam intensity transmitted by intense laser are carried out. The results show that the effective laser range of 10kW is less than 10km, and the aperture and beam quality of the transmitting system need to be strictly controlled. The jitter amplitude of the laser-bearing platform is the main factor affecting the power density of the far-field beam. Small or negligible conditions, turbulence and thermal halo play nearly the same role as far-field beams.
