Operation of compact quantum sensors in field and space implicates challenging requirements on components, subsystems and integration technologies. In our work, we want to realize miniaturized, ultra-stable and ultra-high vacuum (UHV) compatible optical setups, which are integrated inside the vacuum chamber of cold atom sensors and thus lead to a significant reduction of system size and complexity. Besides challenging demands on alignment precision and thermo-mechanical durability, we specifically address UHV-compatibility of our integration technologies and optical components. A versatile UHV qualification system is currently being commissioned, enabling residual gas analysis and measurements of total gas rates down to 5· 10−10 mbar l/s.
Furthermore, a prototype design of an UHV-compatible, crossed beam optical dipole trap setup and its application within a cold atomic quantum sensor is described.
