We present an experiment for quickly producing Bose–Einstein condensates (BECs) of 23Na atoms in a simple crossed dipole trap. The atoms were collected in a magneto-optical trap from a zero-crossing Zeeman slower. The atoms are then transferred to a tightly focused crossed optical dipole trap, and a pure F = 1 BEC of ∼1.1 105 sodium atoms was created by a fast forced evaporation. Our system reliably generates the condensate at a rate exceeding 105 atoms every ∼8s. We also compare the lifetimes of the mixed F = 1 condensate and the spin components (m F = 0, m F = +1).

快速、简单、全光生产旋压钠缩合物

我们提出了一个实验,用于在简单的交叉偶极阱中快速产生23 个Na 原子的玻色-爱因斯坦凝聚体 (BEC) 。原子被收集在一个磁光陷阱中,来自一个较慢的零交叉塞曼。然后将原子转移到紧密聚焦的交叉光学偶极子阱,通过快速强制蒸发产生约 1.1 10 5 个钠原子的纯F = 1 BEC 。我们的系统以每 8 秒超过 10 5 个原子的速率可靠地产生冷凝物。我们还比较了混合F = 1 凝聚物和自旋分量 ( m F = 0, m F = +1)的寿命。
