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.

该实验研究计划旨在通过桌面激光器辐射的相互作用在分子中使用高阶生成，以产生超快，相干x射线。与原子中高次谐波产生的广泛研究不同，分子中高次谐波产生的实验研究还处于起步阶段。 许多有趣的理论预言尚待证实，以了解分子和原子中谐波产生之间的差异。特别是，这项工作将研究谐波产生与对齐的分子。堪萨斯光源激光器，产生3毫焦耳，25飞秒或0.5毫焦耳，7飞秒脉冲，将用于进行研究。该计划的更广泛影响将是基础原子物理研究和超快X射线源在生物学和其他领域的应用。
