Abstract
We have carried out impact experiment of Al mini-flyers, which have been accelerated by high intensity pulsed lasers to generate ultra-high, dynamic pressures. A laser intensity of about 50 TW/cm2 can achieve an impact velocity of 40 km/s, corresponding to a terapascal range of pressure. Laser-shock recovery experiments of hBN and SiC were investigated up to 650 GPa, and recovered samples were compared with previousresults by conventional shock experiments. Analyses of recovered samples reveal some differences in the quenched phase, which may apparently be attributed to short durations of laser-shock compressions.
