Specialized Fiber Collimators: Cooling and trapping atoms by specially developed fiber collimators

The general interest in the investigation of ultra‐cold atoms and their distinct features has been constantly growing over the last few decades [1]. Whereas in the beginning, the process of cooling down presented the major challenge, now the extraordinary features of these ultra‐cold systems — for example Bose‐Einstein‐Condensates‐motivate researchers world‐wide to look closer than ever.
