Laser-Induced Shock Compession

The interdependence of pressure and temperature in the shock compression limits the achieving sufficiently high pressures without the heating of the test material. Shock compression of a precooled substance also does not lead to a reduction of temperature. In other words, the region of the P–T diagram immediately adjoining the Ρ-axis is in principle inaccessible in shock-wave experiments. However, the dynamic compression at P ≥ 100 GPa is important for studying the metallization of dielectrics, including condensed gases, for the reduction of residual temperatures after intense shock loading, and for the prevention of the annealing of the high-pressure phases formed and the decomposition of the newly formed chemical compounds, etc.
