Research Focus

The aim of our work is to expand knowledge about quantum systems through our fundamental research with the main focus on the manipulation and control of these systems. We develop lasers and their capabilities with a view to creating new applications and promoting their use in sensor technology. We also have cooperation partners in the industry in this area.
