Atomic cells are required as sensitive quantum measurement systems, for example for atomic clocks, magnetometers, gyroscopes or in optical spectroscopy. Previously feasible silicon-based cells are limited in size (< 10 mm) due to the manufacturing process and only allow very small one-dimensional interaction paths for evaluating the system with a correspondingly high signal-to-noise ratio. The project therefore aims to develop a technology for the defined and reproducible production of glass atom cells. Laser beam welding with ultrashort pulses will be used for this purpose. With this process, glass can be hermetically welded without filler material and without heating the material, thus producing atom cells with defined pressures. The atom cells produced in this way should offer significantly higher measurement accuracy and better optical accessibility. The process developed in the project should therefore help to enable the use of quantum systems in commercial applications.
