中文摘要：
在我们建立的铯原子双磁光阱实验装置上，采用连续激光将气室磁光阱中冷却并俘获的冷原子输运到超高真空磁光阱。在前期利用近共振弱光研究原子输运的工作基础上，我们将输运激光的负失谐量扩展到约2．0GHz，并增大了输运光功率，对冷原子的输运作了实验研究。结果表明：在大负失谐情形下，较强的输运光使冷原子输运更为有效，归因于输运光束对原子的偶极力造成对冷原子的导引作用。
英文摘要：
We have established a cesium double magneto-optical trap （double MOT） system, and realized transferring cold atoms from the vapor-cell MOT to the ultra-high-vacuum （UHV） MOT by continuous transfer laser. On the base of our former work on transferring atoms by weak resonance laser, we extended red detuning of transfer beam to 2.0 GHz, and increased the laser power. We have studied on the transportation of cold atoms. It is demonstrated that the stronger laser power would make the transportation much more efficient if the detuning is far off-resonance. It is induced by the confinement and guidance of cold atoms due to the transverse dipole force of the transfer beam.
