With the folding target and double-step target,the propagating character of shock wave driven by an inclined-incident (with angle of ～45°) laser was studied on “Shenguang-Ⅱ” high-power laser facility.The result indicated that the shock wave in the target still propagates along the vertical direction to the target surface.Also the same result was verified indirectly by another experiment based on the measurement for spatial intensity distribution of x-ray radiated from jet plasmas.
