Because of special beam intensity distribution of Shenguang Ⅱ laser facility, the equable-width-element cylindrical lens array line-focus system cannot lead to satisfying line-focus. It′s essential to calculate the effect of beam distribution. In this article, optimized design and manufacture of inequable-width-element cylindrical lens array line-focus system were done. It can make very good uniform line-focus with relevant experimental scheme. Good results of X-ray laser experiment proved the resultful design.
