Optical parametric oscillator (OPO) laser system

新的激光系统将用于扩展我们对氦纳米液滴超冷环境中分子间力和反应的研究。通过新的激光系统，我们扩展了我们的频率范围，使我们能够观察到OH伸缩模式，这是氢键的敏感探针。我们的目标是检测高活性化合物，如卡宾或锂碱，与水的分子相互作用，并研究其溶剂化过程。我们希望通过研究具有明确数量的水分子的电子转移反应，来全面了解溶剂在催化过程中的作用。此外，今后的研究将侧重于与大气化学有关的分子聚集体。新的OPO激光系统将是我们氦纳米液滴分离（HENDI）装置的一个很好的补充，并将使我们能够解决分子聚集体研究中的重要问题。

The new laser system will be used to extend our studies on intermolecular forces and reactions in the ultracold environment of helium nanodroplets. With the new laser system, we extend our frequency range, allowing us to observe the OH-stretching modes, which are sensitive probes for hydrogen bonding. We aim to detect the molecular interaction of highly reactive compounds, such as carbenes or lithium bases, with water and investigate their solvation processes. We want to build a comprehensive picture of the role of the solvent in catalytic processes by studying electron transfer reactions with well-defined number of water molecules. Furthermore, future studies will focus on molecular aggregates with relevance to atmospheric chemistry. The new OPO laser system will be an excellent addition to our helium nanodroplet isolation (HENDI) setup and will allow us to tackle important problems in the study of molecular aggregates.
