The requested laser system is essential for experiments on transient structural dynamics of molecules and of chemical reactions on ultrafast time scales. Three complementary research directions are planned within a research group that I propose to establish via a Heisenberg professorship that is applied for in parallel: (1) Laser-Induced Electron Recollision and Diffraction, (2) Laser-Driven Coulomb Explosion Imaging, and (3) Transient Absorption of Extreme Ultraviolet (XUV) Light. The specifications of the laser system (high-repetition rate amplified femtosecond laser with two optical parametrical amplifiers for frequency conversion) allow the generation of ultraviolet pump and strong-field / XUV probe pulses under conditions which enable coincidence measurements.

请求的激光系统对于超快时间尺度上分子的瞬时结构动力学和化学反应的实验至关重要。我建议在一个研究小组中提出三个互补的研究方向，该研究小组旨在通过海森堡教授职位建立，该教授的并行应用：（1）激光诱导的电子回忆和衍射，（2）激光驱动的库仑爆炸成像，以及（3）极端紫外线（3）极端紫外线（XUV）光线。激光系统的规格（具有两个光学参数放大器的高重复速率扩增飞秒激光器用于频率转换）允许在启用重合测量的条件下产生紫外泵和强场 / XUV探测脉冲。
