在二维(2D)和三维(3D)的情况下，我们对三光束和四光束的位形进行了理论研究，推广了著名的一维LIN⊥LIN(两个反向传播的光束具有交叉的线偏振)和磁辅助西西弗效应冷却方案。结果表明，布拉韦晶格是如何由激光束的传播方向决定的，而基是与入射波的偏振有关的。计算了Jg=1/2→Je=3/2跃迁在不同角度和极化组态下的光学势，并预测了原子在单个微米级势垒中运动的一些特征。
We present a theoretical study of three-and four-beam configurations that generalize, in the two-dimensional (2D) and three-dimensional (3D) cases, the well-known 1D lin⊥ lin (two counterpropagating beams having crossed linear polarizations) and magnetic-assisted Sisyphus effect cooling schemes. It is shown how the Bravais lattice is determined from the propagation directions of the laser beams while the basis is associated with the polarizations of the incident waves. The optical potentials are calculated for a J g= 1/2→ J e= 3/2 transition for a variety of angular and polarization configurations and some of the characteristics of the atomic motion inside a single micrometer-sized potential well are predicted.
