AB: Laser-induced shock-wave techniques complement conventional shock-wave and static loading techniques in the study of equation of state, phase transitions, high-pressure physics and chemistry, and mechanical properties of condensed matter under extreme pressure and temperature conditions. Furthermore, the strain rates in laser experiments can be varied over a wide range, thus making them suitable for geophysical research in Earth and planetary materials, and impact behavior. We review some techniques in laser-induced shock waves and commonly-associated diagnostics, including direct laser drive, laser-launched flyer plate, quasi-isentropic loading, point and line imaging velocity interferometry, transient x-ray diffraction, spectroscopy and shock recovery. We will also show exemples of measurements from studies of equations of state, spall, and phase transitions. *Work performed under the auspices of the US Department of Energy under contract No. W-7405-ENG-36.
