The generation of a plasma with an ultrahigh energy density of 1.2 GJ/cm3(which corresponds to about 12 Gbar pressure)is investigated by irradiating thin stainless-steel foils with high-contrast femtosecond laser pulses with relativistic intensities of up to 1022 W/cm2.The plasma parameters are determined by X-ray spectroscopy.The results show that most of the laser energy is absorbed by the plasma at solid density,indicating that no pre-plasma is generated in the current experimental setup.
