| 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. |

| Keywords: | laser induced shock PVDF gauges attenuation |
