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.

Nd∶doped-glass-based sub-picosecond laser system with the maximum peak power of greater than 20 tara watts and the energy on target surface of 16 J is accomplished by using the chirped laser pulse amplification technology. While the laser pulse is focused by an off-axis parabolic mirror, the power density on target surface of approximately 2×10 18 W/cm 2 is acquired. In the performed neutron experiment, a C 8D 8 plate target is placed on the focal spot of the off-axis parabolic mirror. The maximum neutron yield for a single shot reaches 2.4×10 4. Still some other related problems are discussed
