100 kW固体激光中继镜系统模拟

Simulation of 100 kW Solid-State Laser Relay Mirror System

建立了中继镜系统模型,并进行了一定的近似,存某地区特定大气条件下,利用激光大气传输四维程序及相关程序模块,分别计算了固体激光中继镜系统和常规地基高能激光系统对1 km高度,1 km/s飞行速度目标的作用效果。根据中继镜系统对目标可作用时间长的特点,选取常规激光系统和中继镜系统的破坏阈值分别为3 cm桶中功率28.27 kW和5.655 kW,分析得出常规高能激光系统可作用目标的最大水平距离为4.6 km,中继镜系统可作用目标的最大水平距离为11.3 km。与常规高能激光系统相比,中继镜系统降低了大气对激光的影响,拓宽了激光系统的作用范围。

The model of laser relay mirror system is established, to calculate the effect of telescope solid-state laser relay mirror system and the conventional high energy laser system on 1-km altitude, 1-km/s speed target by using the ＂4-D＂ code of the laser atmosphere propagation. Because the relay mirror system has long time effect on the target, its damage threshold standard for 3-cm bucket power is 28.27 kW and 5. 655 kW. The analysis results show that the coverage range of the conventional high energy laser system is 4.6 kin, and the coverage range of laser relay mirror system is 11.3 km. Compared with the conventional high energy laser system the relay mirror system reduces the influence of the atmosphere on the laser, and opens up the coverage range of the laser system.
