钻石的Hugoniot数据是用0.5-2Tpa范围内的激光驱动冲击波获得的。用2.5 ns的激光脉冲直接照射到铝驱动板上，产生了强烈的冲击波。用光学测量方法测定了金刚石和铝中的冲击波速度。粒子速度和压力是使用阻抗匹配法和已知的Al Hugoniot得到的。在实验误差范围内，得到的钻石Hugoniot数据与Pavlovskii Hugoniot数据在TPA范围内的外推没有明显差别。
Hugoniot data of diamond was obtained using laser-driven shock waves in the terapascal range of 0.5–2TPa. Strong shock waves were generated by direct irradiation of a 2.5ns laser pulse on an Al driver plate. The shock wave velocities in diamond and Al were determined from optical measurements. Particle velocities and pressures were obtained using an impedance matching method and known Al Hugoniot. The obtained Hugoniot data of diamond does not show a marked difference from the extrapolations of the Pavlovskii Hugoniot data in the TPa range within experimental errors.
