Absorption-free Bragg reflector has been studied in ions doped in crystals. We propose a new scheme using Zeeman sublevels of atoms to construct an absorption-free Bragg reflector with practical laser power. Its spatial period of refractive index equals half of the wavelength of the incident standing-wave coupling light. The proposal is simulated in a helium atom scheme, and can be extended to alkali earth atoms.
在掺杂于晶体中的离子中研究了无吸收布拉格反射器。我们提出了一种新方案，利用原子的塞曼子能级来构建具有实际激光功率的无吸收布拉格反射器。其折射率的空间周期等于入射驻波耦合光波长的一半。该方案在氦原子方案中进行了模拟，并且可以扩展到碱土原子。
