Direct imaging of shock wave splitting in diamond at Mbar pressure
Fig. 1. Outline of pump–probe experiment for visualization of elastic–plastic shock wave (SW) evolution in diamond with submicrometer spatial resolution. A shock wave is driven by a focused drive laser (yellow) into a target consisting of an ablator (25
