This project aims to create multi-colour, ultrashort, highly coherent, bright pulses of soft X-rays based on high-harmonic generation in a table-top multiple-section gas cell. Studying multi-electronic and non-adiabatic processes and other fundamental aspects such as multi-electronic correlations and non-Born-Oppenheimer vibronic couplings in complex molecules is a major challenge in current ultrafast photochemistry research. This project will use multiple driving pulses with different carrier frequencies to control the spectral properties and time delay of the pulses. It will use the soft X-ray source to develop an ideal platform for studying multi-electronic and non-adiabatic processes, multi-electronic correlations and non-Born-Oppenheimer vibronic couplings in complex molecules. This is expected to advance materials science, paving the way to soft X-ray technologies.

该项目旨在创建基于桌面多节气室中高次谐波产生的多色，超短，高度相干，明亮的软X射线脉冲。研究复杂分子中的多电子非绝热过程以及多电子关联和非Born-Oppenheimer振动耦合等基本问题是当前超快光化学研究的一个主要挑战。该项目将使用具有不同载波频率的多个驱动脉冲来控制脉冲的光谱特性和时间延迟。它将使用软X射线源开发一个理想的平台，用于研究复杂分子中的多电子和非绝热过程，多电子相关性和非Born-Oppenheimer振动耦合。这有望推动材料科学的发展，为软X射线技术铺平道路。
