从理论上研究了两束激光倏逝波在介质棱镜表面传播形成的陷阱，它将原子限制在沿着垂直于棱镜方向的一个莫尔斯势中。我们考虑一个加载过程的基础上的西西弗斯效应，其中一个单一的自发拉曼跃迁参与。我们表明，这是可能的，以这种方式实现一个有效的加载的莫尔斯势的基态，从而得到一个准二维原子气体在表面的电介质。
We investigate theoretically a trap formed by two laser evanescent waves propagating at the surface of a dielectric prism, which confine the atoms in a Morse potential along the direction perpendicular to the prism. We consider a loading process based on the Sisyphus effect, in which a single spontaneous Raman transition is involved. We show that it is possible to achieve in this way an efficient loading of the ground state of the Morse potential, and to get thus a quasi-bi-dimensional atomic gas at the surface of the dielectric.
