Abstract

Based on the characteristics of the Fourier and inverse Fourier transform of special functions, a double binary optics composite system is proposed to realize focusing with high uniformity, which is insensitive to the distortion of the input laser beam. Yang-Gu's algorithm combined is used for optimization design. The deviation caused by diffraction is corrected by iterative optimization. High quality focus with efficiency higher than 90%, uniformity better than 3% (rms), filling factor (FF) higher than 90% is obtained. Simulation calculation shows that it is a promising way to complement ICF uniform illumination.
