Due to the recent progress in the fields of ultra-cold molecules and optical metrology the precise coherent manipulation of molecular internal, i.e. rotational and vibrational, quantum states has come into reach for experiments. The new technologies will provide the means to transfer theoretical concepts and experimental techniques from atom interferometry to a new field, namely molecular internal state quantum interferometry. As atom interferometry has already proven to be the most powerful metrology tool nowadays, molecular interferometry will have strong impact on fields like precision molecular spectroscopy, test of molecular QED, and possibly on tests of Special and General Relativity.The goal of this research project is to develop a complex laser system for coherent manipulation and precision spectroscopy of ultra-cold molecules, in particular of the HD+ molecular ion. It combines latest developments in optical metrology, i.e. fs-optical frequency combs, with advanced diode laser concepts. The development of these technologies is not only relevant for molecular interferometry but is also of general interest for atomic and molecular precision spectroscopy.

由于超冷分子和光学计量学领域的最新进展，分子内部，即转动和振动量子态的精确相干操纵已经进入实验阶段。这些新技术将提供将理论概念和实验技术从原子干涉计量学转移到一个新的领域，即分子内态量子干涉计量学的手段。由于原子干涉测量已经被证明是当今最强大的计量工具，分子干涉测量将对精密分子光谱、分子量子电动力学测试以及特殊和一般关系测试等领域产生重大影响。本研究项目的目标是开发一种复杂的激光系统，用于超冷分子，特别是HD+分子离子的相干操纵和精密光谱。它结合了光学计量学的最新发展，即飞秒光学频率梳，以及先进的半导体激光器概念。这些技术的发展不仅与分子干涉计量学有关，而且对原子和分子精密光谱学也有普遍的兴趣。
