我们报道了第一个基于2D/3D磁光陷阱(MOT)方案的实验装置，它可以产生玻色-爱因斯坦凝聚体和几个Yb同位素的简并费米气体。我们的装置不需要塞曼速度较慢，并且提供了同时产生其他原子物种的超冷样品的灵活性。此外，这种非同寻常的光学访问有利于未来的光学晶格实验。强S-1(0)->；P-1(1)跃迁上的2D-MOT直接从原子分配器捕获Yb，并在窄的S-1(0)->；P-3(1)互组态上加载3D-MOT。随后，原子被转移到交叉光学偶极陷阱，并蒸发冷却到量子简并。(C)2013 AIP出版有限责任公司。[http://dx.doi.org/10.1063/1.4802682]
We report on the first experimental setup based on a 2D-/3D-magneto-optical trap (MOT) scheme to create both Bose-Einstein condensates and degenerate Fermi gases of several ytterbium isotopes. Our setup does not require a Zeeman slower and offers the flexibility to simultaneously produce ultracold samples of other atomic species. Furthermore, the extraordinary optical access favors future experiments in optical lattices. A 2D-MOT on the strong S-1(0) -> P-1(1) transition captures ytterbium directly from a dispenser of atoms and loads a 3D-MOT on the narrow S-1(0) -> P-3(1) intercombination transition. Subsequently, atoms are transferred to a crossed optical dipole trap and cooled evaporatively to quantum degeneracy. (C) 2013 AIP Publishing LLC. [http://dx.doi.org/10.1063/1.4802682]
