我们报告了用于反射缓慢移动的中性原子光束的磁镜开发的最新进展。描述了构建具有微米级周期性的周期性磁性结构的不同方法，包括使用通过光刻制造的载流线阵列、通过电子束光刻制造的凹槽铁磁结构以及通过聚焦二极管激光束在磁光薄膜上记录的磁性结构。给出了自由落体激光冷却铯原子从这些微加工磁镜反射的结果。
We report recent progress on the development of magnetic mirrors for reflecting beams of slowly moving neutral atoms. Different approaches for constructing periodic magnetic structures with micron-scale periodicities are described, including the use of arrays of current-carrying wires fabricated by photolithography, grooved ferromagnetic structures fabricated by electron-beam lithography, and magnetic structures recorded on magneto-optical film by a focused diode laser beam. Results on the reflection of free-falling laser-cooled caesium atoms from these microfabricated magnetic mirrors are presented.
