“…Compared with the shock wave driven by mechanical impact, a laser-driven shock wave has a higher repetition rate and better stability, and therefore it has been used widely in various fields, for instance, in the study of molecular dynamics, [1 -3] the improvement of the mechanical properties of solids [4,5] and the synthesis of many materials at high pressure. [6,7] In addition, a laser-driven shock wave is useful in the nanotechnology, such as microfabrication and removal of nanoparticles. [8,9] Usually, the duration of the laser-driven shock wave is extremely short, and therefore the time-resolved spectroscopic technique is an effective tool for the investigation of such a shock phenomenon.…”
