研究了激光与俘获原子相互作用并与基态能级和激发态能级的不同跃迁共振时，Rb磁光陷阱(MOT)布居的变化。冷却方案外的激光激发会导致MOT布居的损失，而当激光调谐到与陷阱周期有关的跃迁时，则会增加陷阱布居。这项实验是用少量被捕获的原子(100到10000个)进行的。讨论了我们操纵不同超精细态原子布居的能力。
We study the rubidium magneto-optical trap (MOT) population changes induced by a laser beam interacting with the trapped atoms and resonant with different transitions from both the ground and the excited trap levels. Laser excitation outside the cooling scheme induces losses in the MOT population, while the laser increases the trap population when tuned to transitions linked to the trapping cycle. The experiment is performed with a small number of trapped atoms (100 to 10 000). A discussion of our ability in manipulating the atomic population of different hyperfine states is reported.
