Precision Measurements of Photoelectrons and Radiation From Atoms in Ultrastrong Fields

该项目涉及对单个原子与超强激光脉冲相互作用的一系列精确测量。在这些激光脉冲中，电场比将原子聚集在一起的电场强得多。这些研究将产生一套详细的、高动态的场-原子相互作用范围测量。这门科学直接关系到原子、分子和光学物理中正在进行的实验和理论工作的基础课题，包括多电子现象、磁场-原子相互作用、相对论动力学和超快X射线辐射。超强激光科学的前沿横跨等离子体物理、聚变科学、原子物理、光学科学、激光技术和阿秒X射线辐射。这项研究未来的实际应用包括为激光聚变和基于激光的加速器内的过程提供测量。这些基础科学测量也为未来辐射源的开发和应用提供了基础。超强场辐射具有传统X射线源所不具备的特性。需要这种新的X射线源在分子和电子水平上可视化反应路径和动力学，这是传统技术无法观察到的。现代光学的教学和培训通过开发本科生实验室和讲授演示来加强。这些新资源包括为工程和物理专业学生提供的全息术、衍射学和显微光学。

This project involves a series of precision measurements of individual atoms interacting with ultrastrong laser pulses. In these laser pulses, the electric field is much stronger than the electric fields holding the atom together. The studies will result in a set of detailed, high-dynamic range measurements of the field-atom interaction. The science has direct bearing on topics fundamental to ongoing experiment and theory efforts in atomic, molecular, and optical physics including multi-electron phenomena, magnetic field-atom interactions, relativistic dynamics, and ultrafast X-ray radiation.The frontiers of ultra-intense laser science stretch across plasma physics, fusion science, atomic physics, optical science, laser technology, and attosecond X-ray radiation. Practical future applications of the research include providing measurements for processes within laser fusion and laser based accelerators. These basic science measurements also provide a footing for future radiation source development and applications. Radiation from ultrastrong fields has characteristics not possessed by traditional X-ray sources. Such new X-ray sources are needed to visualize reaction pathways and dynamics at the molecular and electronic level not observable with conventional techniques. Teaching and training in modern optics is enhanced by developing undergraduate laboratory and lecture demonstrations. These new resources include holography, diffractive and micro-optics for students in engineering and physical sciences.
