Continuous optical loading of a Bose-Einstein Condensate

L. Santos, F. Floegel, T. Pfau, M. Lewenstein

摘要:

分析了热库中原子通过自发发射连续抽运进入玻色-爱因斯坦凝聚体的过程。我们考虑的情况下,原子的三能级$Λ$计划,其中一个原子的跃迁有一个非常短的寿命比另一个。我们发现,在这种情况下,光子重吸收在稠密的云可以被认为是可以忽略的。如果忽略非弹性过程,我们发现光抽运可以用来连续加载和填充玻色-爱因斯坦凝聚体,即提供了一种实现连续原子激光的可能途径。

英文摘要:

The continuous pumping of atoms into a Bose-Einstein condensate via spontaneous emission from a thermal reservoir is analyzed. We consider the case of atoms with a three-level $Λ$ scheme, in which one of the atomic transitions has a very much shorter life-time than the other one. We found that in such scenario the photon reabsorption in dense clouds can be considered negligible. If in addition inelastic processes can be neglected, we find that optical pumping can be used to continuously load and refill Bose-Einstein condensates, i.e. provides a possible way to achieve a continuous atom laser.
