| 中文摘要 | 为了提高高功率激光系统的整体效率和充分利用光能,需要对前端注入的高斯光束进行空间整形,实现驱动器终端激光的均匀化输出。采用振幅型二元面板对激光光束进行空间强度整形,利用误差扩散法进行了理论设计,数值摸拟了整形效果,同时讨论了面板加工误差以及空间滤波器的小孔大小等因素带来的影响。根据理论设计,分别加工了反高斯透射率分布和抛物线透射率分布的二元面板,并进行了整形实验,实现了各自的整形功能,并做了误差分析。实验证明二元面板能对激光光束的空间强度分布实现了精确的整形。; In order to improve the energy efficiency of the inertial confined fusion (ICF) high-power laser system and use the optical energy sufficiently, it is necessary to convert Gaussian laser beam into uniform beam, or into parabolic-like beam to precompensate the spatially dependent gain of the Nd:glass amplifiers, for the sake of uniform output distribution at the target. The intensity control is obtained with panels composed of binary pixelated arrays of metal pixels, which was designed by error diffusion method. The shaping effect is numerically simulated. The factors, which will influence the shaping effect, such as mismachining of the panel and size of the pinhole of the spatial filter are discussed. An anti-Gaussian distribution and a parabolic distribution binary panels are fabricated. The experimental shaping result is given and the error is analyzed. Binary panels are proved to be excellent shaping elements in modeling the intensity of laser. |
