This experimental research program is aimed at investigations of atom-light interactions in radically nonperturbative, ultrahigh laser intensities up to 10^19 W/cm^2. The studies are among the first to extend these studies into ultrahigh field intensities and are focused on atomic and optical physics. The science has direct bearing on topics fundamental to Atomic, Molecular, Optical, and Plasma physics, including new multi-electron phenomena, magnetic field-atom interactions, relativistic continuum dynamics, and ultrafast radiation from laser-atom interactions. The broader impact of the program will be on fourth generation XUV and X-ray radiation light sources and applications as wide-ranging as attosecond science and time resolved x-ray diffraction.

这个实验研究计划的目的是研究在强度高达10^19 W/cm ^2的完全非微扰的飞秒激光中原子与光的相互作用。这些研究是第一批将这些研究扩展到量子场强度的研究，重点是原子和光学物理。该科学直接关系到原子，分子，光学和等离子体物理学的基本主题，包括新的多电子现象，磁场原子相互作用，相对论连续动力学和激光原子相互作用的超快辐射。该计划将对第四代XUV和X射线辐射光源以及阿秒科学和时间分辨X射线衍射等广泛应用产生更广泛的影响。
