论文摘要
我们在光学评估旨在引导冷原子的菲涅尔区板（FZP）。相对于陷阱深度，FZPS产生的各种环模式的成像在3％的环的最明亮部分中给出了平均RMS误差。该残留物将归因于成像系统，入射光束形状和FZP制造公差。电势的轴向传播是通过实验和数值模拟呈现的，这说明了原子引导的前景而无需轻板。
We optically assess Fresnel zone plates (FZPs) that are designed to guide cold atoms. Imaging of various ring patterns produced by the FZPs gives an average RMS error in the brightest part of the ring of 3% with respect to trap depth. This residue will be due to the imaging system, incident beam shape and FZP manufacturing tolerances. Axial propagation of the potentials is presented experimentally and through numerical simulations, illustrating prospects for atom guiding without requiring light sheets.
