论文摘要
在船尾gerlach（SG）实验中的Zeeman Hyperfine状态依赖性力已被利用，以分离和检测具有冷原子云中不同Zeeman超细态的原子。利用这种SG技术，我们对原子云中不同Zeeman Hyperfine状态的原子进行了定量估计，这有助于优化原子的光学泵送以有效制备原子状态。使用优化的光学泵送，将近92美元的冷$^{87} rb $原子从Atom-Chip上的灰色磁光陷阱（G-MOT）中的原子进行了光学泵送到可怕的Zeeman Hyperfine Hyperfine Satem $ \ ket $ \ ket {f = 2，f = 2，\，m_，m_ f = 2，\，m_ f = 2，\，m_ {f} $。这些光学泵送原子已被困在原子芯片表面附近的Ioffe-pritchard磁陷阱中。
The Zeeman hyperfine state dependent force in a Stern-Gerlach (SG) experiment has been exploited to separate and detect atoms having different Zeeman hyperfine states in a cold atom cloud. Utilizing this SG technique, we have made the quantitative estimate of atoms in different Zeeman hyperfine states in an atom cloud, which has been helpful in optimizing the optical pumping of atoms for efficient preparation of atomic state. Employing an optimized optical pumping, nearly $92 \% $ of cold $^{87}Rb$ atoms from a grey magneto-optical trap (G-MOT) on atom-chip have been optically pumped to the trappable Zeeman hyperfine state $\ket{F=2, \, m_{F} = +2}$. These optically pumped atoms have been trapped in an Ioffe-Pritchard magnetic trap near the atom-chip surface.
