Abstract

Abstract

Laser-induced stress waves can deliver ramp compression on solid materials with very high strain rates, and it is one of the newly-developed dynamic high-pressure methods in decades. Distinct from the conventional methods, laser ramp compression can reach terapascal pressures smoothly from ambient pressure with a high strain rate 10⁶-10⁹ s^-1, but the sample is still in solid state. During the rapid loading process, the thermodynamic state, dynamic characteristics, and in situ microstructure can all be probed by the advanced diagnostic technology. This method is becoming an important and new approach to further investigation on high-pressure physics, equation of state, and rate-dependent material dynamics. In this paper, the history, principle, diagnostics and main breakthroughs of laser ramp compression are reviewed and expected.
