英文摘要	We transfer cold Rb-87 atoms from a red vapour cell chamber to a spatially seperated UHV magneto-optical trap (MOT) with the assistance of a red-detuned optical guiding beam and normal push beam. Efficient optical guiding of the cold atoms is observed within a small detuning window. A pulsed optical guiding beam enhances the transfer efficiency and hence allows us to collect more atoms in UHV MOT in a shorter time, which favourable for our experiment of achieving Bose-Einstein condensates (BEC). Besides the easy operation, another advantage of this optical guiding technique is also demonstrated such that slower atomic beams may be efficiently transferred along horizontal direction. This study is a direct application of the optical guiding technique is a powerful tool.
