我們已成功的將銣-85與銣-87兩種原子同時捕捉在一個磁光陷阱中。以光學幫浦法做為量測原子數目的工具，系統地最佳化實驗參數，使得雙原子磁光陷阱中每種原子數目皆可達6×108。並利用原子放出的螢光來分析兩種原子在空間中的分布。最後用實驗驗證光脈衝因電磁波引發透明效應而減慢的理論預測。

We have demonstrated a magneto-optical trap that simultaneously captures two different isotopes - rubidium-85 and rubidium-87, and atom numbers of 6×10^8 for each atom are trapped. The single-specie and double-species MOTs are described. We optimize them by directly measuring the number of atoms with the optical-pumping technique. An intensity profile of the spatial atomic distributions, as observed by the CCD, is discussed. Finally, we performed the experiments of slow-light, which is based on the electromagnetically induced transparency, and the theoretical prediction is in agreement with the measurements.
