摘　　要：针对高功率板条激光放大系统光束整形的需要,基于CODE V软件对一维光束整形系统进行仿真,光束整形方向输出光光学传递函数接近衍射极限。光束整形方向视场0.5 mrad时,引入波像差为0.105λ。利用四波剪切干涉仪测量He-Ne光以及光纤种子光整形后波前,P-V值变化小于0.25λ,RMS变化小于0.05λ。For the requirement of high power slab laser system＇s beam shaping,one-dimensional beam shaping system is simulated by CODE V software, optical transfer function of beam shaping direction of the output light is close to the diffraction limit. When the beam shaping field is 0.5 mrad,the wave aberration is 0.105A. He-Ne light and fiber seed light wavefront after shaping are measured by using four wave shear interferometer, P-V value changes less than 0. 25A, RMS value changes less than 0.05A.
