采用条纹时间分辨X射线阴影术研究了六束1.05 μm激光在辐照度为1013 W cm-2的情况下烧蚀球壳靶的内爆。加速度测量确定消融压力。一维模拟结果表明，对于表面扰动为±0.05 Δ r的壳体，随着壳体长宽比r Δ r从10增加到110，内爆的退化程度逐渐增加。
The implosion of spherical-shell targets driven ablatively by six 1.05-μm laser beams at an irradiance of∼ 10 13 W cm− 2 has been studied by streak time-resolved x-ray shadowgraphy. Measurements of acceleration determined the ablation pressure. Departures from one-dimensional simulations showed increasingly degraded implosions as the shell aspect ratio r Δ r was increased from 10 to 110 for shells with surface perturbations of±0.05 Δ r.
