Abstract
Using uniform illumination of a high‐power laser on inclined plane targets and impedance‐match targets, we have studied the shock stability in Al and measured the shock adiabats of Fe and SiO2 by recording the shock luminant signals from the back surface of the targets with an optical streak camera. Experiments show that the shock wave is steady in the thickness range of (20–40) μm in Al. The reliable shock adiabats of Fe and SiO2 were obtained in the pressure range of (0.35–0.82)TPa and (0.21–0.41)TPa, respectively.Keywords
