Laser-driven shock wave experiments have been performed to determine equation of state (EOS) of copper using impedance matching technique in the pressure range 8–11 Mbar. A 2J/200 ps Nd : YAG laser beam is used to induce dynamic  shocks in aluminium foil (reference material) and Al–Cu layered targets. EOS of copper is obtained at shock pressures of 8.9 Mbar and 10.4 Mbar with a pressure enhancement of ~1.66 at Al–Cu interface. The xperimental data points are consistent with the predictions of the EOS model based on first principle theory and are also in close agreement with the simulation results obtained using one-dimensional radiation hydro-code MULTI that uses SESAME data tables for EOS and opacity values.
