在“神光 Ⅱ”高功率激光装置上 ,利用弯折靶、双台阶靶实验及通过对等离子体喷射状态的实验测量 ,研究了激光斜入射情况驱动的冲击波传播特性 .结果表明 ,即使在大角度 (约 4 5°)斜入射的激光驱动下 ,靶材料中的冲击波依然是沿着靶面法线方向传播的 ,并能形成很好的一维正击波 . In the “SG Ⅱ” high-power laser device, the shock wave propagation characteristics driven by laser oblique incidence are studied by using bending target, double-step target experiment and experimental measurement of plasma jet state. The results show that even in large Angle (about 45 °) oblique incident laser drive, the target material in the shock wave is still along the normal direction of the target propagation, and can form a good one-dimensional normal wave.
