Abstract
Laser-driven dynamic compression is used to study matters in extreme conditions. High-pressure and
high-temperature states of matter are generated under the laser-shock compression, of great current
interest for high-energy density physics, planetary sciences, and inertial fusion energy research. At the
high P-T conditions, the micro-structure of material significantly influences the behavior and properties
of material. X-ray free electron laser (XFEL) is a powerful tool to directly observe a structure and to
reveal the time scale of the structural change under the dynamic high pressures. Here we present recent
results of laser-driven high pressure experiments associated with strong shock equation of state and
ultrafast observation of lattice dynamics.
