Results of the first BEC achieved in space published in Nature journal

On January 23, 2017 a Bose-Einstein condensate in space was realized for the first time worldwide. The results of this groundbreaking experiment entitled "Space-borne Bose-Einstein condensation for precision interferometry" were published on 10/18/2018 in the Nature journal. This milestone in quantum optics was made possible, among other things, by micro-integrated laser modules suitable for space applications, which are being developed at FBH [1]. This laser technology for quantum-optical applications in space is continuously being further developed by the Institute. Accordingly, in spring 2018, an iodine-based optical frequency reference was realized in space for the first time [2].
