【摘要】 利用自行研制的ＰＶＤＦ压电膜传感器实时测量了高功率密度脉冲激光辐照到铝材料表面时在靶材中诱导的激光冲击波压力，通过对不同厚度靶板背面冲击波压力的测量获得了激光冲击波在铝材料中的衰减规律，并在ＧＷ／ｃｍ２量级的范围内研究了激光冲击波峰压随激光功率密度的关系更多还原

【Abstract】 High power pulsed laser induced shock wave pressures in aluminum targets are measured with the use of PVDF gauges made by ourselves. The pressure decay of laser induced shock in aluminum is obtained by measuring the pressure on the rear faces of different thickness targets. The shock peak pressures as a function of laser intensity of about GW/cm 2 are reported.更多还原
