Amplified Femtosecond Laser System with High Repetition Rate

所要求的激光系统对于分子的瞬时结构动力学和超快时间尺度上的化学反应的实验是必不可少的。我建议通过一个平行申请的海森堡教授职位，在一个研究小组内规划三个互补的研究方向：(1)激光诱导的电子碰撞和衍射，(2)激光驱动的库仑爆炸成像，以及(3)极端紫外线(XUV)的瞬时吸收。激光系统的规格(带有两个用于频率转换的光学参数放大器的高重复频率放大飞秒激光器)允许在能够进行符合测量的条件下产生紫外线泵浦和强场/XUV探测脉冲。

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.
