High pressure property of MgO under shock compression to 1 TPa
Abstract
Optical property of highly compressed MgO has been investigated using laser-driven smoothly decaying shock wave. Shock Hugoniot and temperature measurements for MgO were performed for the first time in TPa pressure regime. Shock compressed MgO is transparent near 300 GPa, meanwhile it is not highly reflecting up to 1 TPa. This wide range opaque property is not comparable with other crystalline dielectrics.
