Research Areas

The Institut für Quantenoptik focuses on applied and fundamental research in laser physics and the interaction of light and matter. The systems under investigation range from individual cold atoms and molcules all the way to living biological organisms, such as the eye.

The research takes place within five distinct research areas focussing on individual ascpects of the interaction of light and matter.

Atom Optics and Quantum Sensors

The inteaction between light and atomic samples is used to investigate and manipulate these building block of nature. This allows for deep insights in the quantum meachnis of these systems and allows for the contruction of sensors at the quantum limit. More

Biophotonics and Nanotechnology

The area of applied laser physics comprises the activities in medical laser applications, nano structuring and optical component manufacturing. More

Laser Components Department

Research activities in the Department of Laser Components are dedicated to complex optical coating systems of highest precision and quality for laser applications and modern optics. More

Molecular Quantum Gases

Our research focuses on the preparation and study of molecular gases at record-low temperatures of a few hundred Nanokelvin above absolute zero. It is at such low temperatures that quantum mechanics and quantum statistics determines the collective behaviour of the molecular samples. More

Molecules & Lasers

The focus of this research area is the description of the interaction between atoms and molecules. Both cold collisions of atoms as well as in binding properties of molecules can be related closely by molecular potentials. High precision spectroscopic experiments on particle beams enable the determination of these potentials with a higher resolution than in many other experiments. More

Quantum Metrology

By combining spectroscopic techniques with quantum logic methods developed for quantum computation with trapped ions, absolute frequency metrology and coherent control of many-level atoms and molecules is performed. This approach will allow us to  improving current limits on fundamental constants and their temporal variation. More

Trapped-Ion Quantum Engineering

Trapped ions are exceptionally well controllable quantum systems. Manipulating them at the level of single quanta using microwaves and lasers enables for the simulation of quantum many body systems and high precision tests of fundamental symmetries of the Standard Model. More

Ultrafast Laser Optics

Short pulses of laser light enable a fascinating range of experiments including time resolves eperiments on the femtoscond sacle and the production of laser light in the x-ray spectrum. More
