We demonstrate the first guiding of atoms through a hollow-core photonic band-gap fiber. Rb atoms from a thermal oven source travel through 6.1 and 4.0 cm long fibers with a guiding potential 1/e(2) radius of 3.0 microm. When the photon scattering rate is small, the observed guiding efficiency is greater than 70%. An unexpected low-speed cutoff is attributed to inefficient optical coupling.
我们展示了原子首次通过空芯光子带隙光纤的引导。来自热炉源的铷原子穿过长度分别为6.1厘米和4.0厘米的光纤，引导势的1/e(2)半径为3.0微米。当光子散射率较小时，观察到的引导效率大于70%。一个意外的低速截止归因于光耦合效率低下。
