Controlling ionization with light-pulse derivatives

我们探索了激光与物质相互作用的新领域。随着新的短波长强激光源的出现，驱动所谓的非绝热跃迁成为可能，这与众所周知的光效应非常不同。最有趣的是，它们依赖于激光脉冲包络的时间导数。这些转变是理论上预测的，并将在本项目中进行研究。我们的目标是更深入地了解和可能的控制这些转变，最终提出一个实验，将证明这一新现象。

We explore a new field of laser-matter interaction. With the advent of novel intense laser sources at short wavelengths it becomes possible to drive so-called non-adiabatic transitions, that are very different from the well-known photo-effect. Most interestingly, they rely on the time derivate of envelope of the laser pulse. Those transitions where predicted theoretically and will be investigated in this project. We aim for a deeper understanding and a possible control of these transitions, ultimately proposing an experiment which will prove this new phenomenon.
