High order harmonic generation in aligned molecules

这个实验研究项目旨在利用桌面激光器辐射的相互作用，在分子中产生高阶生成，以产生超快、相干的x射线。不同于对原子中高次谐波产生的广泛研究，分子中高次谐波产生的实验研究还处于起步阶段。许多有趣的理论预测还有待证实，以理解分子和原子中谐波产生的差异。特别是，这项工作将研究与排列的分子谐波产生。堪萨斯光源激光器可以产生3毫焦耳（25飞秒）或0.5毫焦耳（7飞秒）脉冲，将用于进行这项研究。该计划的广泛影响将是基础原子物理学研究和超快x射线源在生物学和其他领域的应用。

This experimental research program is aimed at using high-order generation in molecules by interaction of radiation from tabletop lasers for producing ultrafast, coherent x-rays. Unlike the extensive research on high harmonic generation in atoms, the experimental study of harmonic generation in molecules is still in its infancy. Many interesting theoretical predications are yet to be confirmed to understand the differences between harmonic generation in molecules and that in atoms. In particular, this work will study harmonic generation with aligned molecules. The Kansas Light Source laser, which produces three millijoule, 25 femtosecond or 0.5 millijoule, seven femtosecond pulses, will be used to conduct the research. The broader impact of the program will be both the basic atomic physics research and the applications of the ultrafast x-ray sources in biology and other fields.
