This renewal proposal for the study of, "High Intensity Laser-Atom Interactions", calls for a joint theoretical and experimental study of atoms irradiated by intense optical fields. The experiments will focus on high harmonic generation (HHG) and on ionization in intense, short optical pulses. The measurements of harmonic coherence will be extended and high-order harmonics will be used to begin a new series of continuum saturation experiments. Recent findings on harmonic angular distributions will be extended by re-imaging the harmonics which emerge from the focus, measuring their spatial coherence using a Young's two-slit interferometer, and making a high resolution study of the angular spectral distribution. Theoretical work will continue to extract new information about strong-field atomic behavior during MPI and high-harmonic generation.

这一更新的研究建议，“高强度激光-原子相互作用”，要求联合的理论和实验研究的原子照射强光场。 实验将重点关注高次谐波产生（HHG）和强短光脉冲中的电离。 谐波相干性的测量将被扩展，高次谐波将被用于开始一系列新的连续饱和实验。 最近的调查结果谐波角分布将通过重新成像的谐波出现的焦点，测量其空间相干性使用杨氏双缝干涉仪，并作出高分辨率的角光谱分布的研究。 理论工作将继续在MPI和高次谐波产生期间提取关于强场原子行为的新信息。
