High Intensity Laser-Atom Interactions

这项关于“高强度激光-原子相互作用”研究的更新建议要求对强光场照射下的原子进行联合理论和实验研究。实验将集中在高谐波产生（HHG）和电离在强，短光脉冲。将扩展谐波相干性的测量，并利用高次谐波开始一系列新的连续介质饱和实验。最近关于谐波角分布的发现将通过重新成像从焦点产生的谐波，使用杨氏双缝干涉仪测量它们的空间相干性，并对角光谱分布进行高分辨率研究来扩展。理论工作将继续提取关于MPI和高谐波产生过程中强场原子行为的新信息。

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.
