摘要：

We demonstrate the transfer of potassium atoms from a vapor-cell type magneto-optical trap (MOT) to a second MOT up to 75 cm away with the use of a spatially narrow push laser that generates a 40-m/s atomic beam. By adding two-dimensional MOT's (atomic funnels) along the transfer path to generate transverse cooling and compression of the beam, we can consistently transfer 78 +/- 10% of the atoms.
