We have realized a novel atom trap in an axicon (conical hollow) mirror, using a frequency-modulated, single-diode laser. Different spatial distributions of trapped atoms such as a ball and a ring are observed. We show that our numerical simulations are consistent with experimental results. In particular, the ring diameter is found to be approximately the separation between the mirror axis and the magnetic field axis. The axicon trap may be useful as a precooled atom source for cold atomic beams, atom funnels, and atom waveguides.
我们利用调频单二极管激光器在轴锥镜（锥形空心镜）中实现了一种新型原子阱。观察到了诸如球和环等被俘获原子的不同空间分布。我们表明，我们的数值模拟与实验结果一致。特别地，发现环直径大约是镜轴与磁场轴之间的间距。轴锥阱可作为冷原子束、原子漏斗和原子波导的预冷原子源。
