| Abstract: | Being aimed at the condition with ultra nonuniform of near field distribution from "Shenguang Ⅱ" (with none laser intensity in large area), by use of the uniform technique of lens array and by the optimizing design for the system combined with principal focal lens and small lens array, a large spot uniform irradiation on target surface has been realized, also a shock illuminant signal with good planarity in large region is obtained while it drives an aluminium plane target. |
