Abstract： |
The invention relates to a method for generating the atom bean used in atom chip and relative device, wherein, the device comprises a vacuum room, an atom source, a two-dimensional micro adjusting platform, a magnetic iron and inner and outer light paths. The inner and outer light paths comprise a main laser and a re-pump laser; the vacuum room is mounted with a 1/4 wave plate reflector group with a hole in center and a direct-guide group; the magnetic light well uses the optical pump laser and the re-pump laser to prepare the atom into optimized weak field scanning state. The invention has small volume and simple structure, while it can supply the optimized weak field scanning state to the atom chip with the atom beam whose longitudinal speed is lower and uniform, transverse speed is nearly zero and density is high. The invention can be used in the guide, wave-division, interference and the Bose-Einstein Coagulation (BEC). |
