It is proposed to construct a far-detuned 3-dimensional optical lattice that can act as an atomic trap. Cooling of the atoms in the trap will be achieved by successive vibrational excitation and de-excitation in the vibrational wells set up by the optical waves. Once the atoms have been appropriately cooled, they will be used for precision measurements of atomic properties. In addition, vibrational cooling of two atoms at a single lattice site will be used as the starting point for the creation of cold, trapped molecules.

提出了一种可以作为原子陷阱的远失谐三维光学晶格。 阱中原子的冷却将通过光波建立的振动威尔斯阱中连续的振动激发和去激发来实现。 一旦原子被适当冷却，它们将被用于原子性质的精确测量。 此外，两个原子在单个晶格位置的振动冷却将被用作创建冷的捕获分子的起点。
