观测了不同约束层材料及不同靶材表面特征情况下产生的激光冲击波。实验发现 ,约束层对激光冲击波的脉宽有显著的展宽作用 ,且冲击波的峰压值随约束层材料的声阻抗的增大而增大。另外 ,研究了表面涂层对冲击结果的影响 ,重新认识了其作用。针对于实际应用 ,还试验了曲面靶材的冲击强化 ,讨论了约束结构的有效性问题。 The laser shock waves generated by different constrained layer materials and the surface features of different targets were observed. The experimental results show that the confinement layer has a significant broadening effect on the pulse width of the laser shock wave, and the peak pressure value of the shock wave increases with the acoustic impedance of the constrained layer material. In addition, the impact of the surface coating on the impact results was studied, and its effect was re-recognized. For the practical application, the impact enhancement of the curved target is also tested, and the validity of the constrained structure is discussed.
