论文摘要
我们证明了抗生素环丙沙星和染料分子在厚的光学光栅处的Bragg衍射。观察到的模式显示出单个显性衍射顺序，其预期依赖性对入射角角度以及未裂纹和衍射梁之间的振荡人口转移。我们达到了$ 14 \ hbar k $（光子矩）的同等振幅分裂和$ 18 \ hbar k $的最大动量转移。这为高效的大摩托束分裂和镜子铺平了道路，用于热和复杂的分子。
We demonstrate Bragg diffraction of the antibiotic ciprofloxacin and the dye molecule phthalocyanine at a thick optical grating. The observed patterns show a single dominant diffraction order with the expected dependence on the incidence angle as well as oscillating population transfer between the undiffracted and diffracted beams. We achieve an equal-amplitude splitting of $14 \hbar k$ (photon momenta) and maximum momentum transfer of $18 \hbar k$. This paves the way for efficient, large-momentum beam splitters and mirrors for hot and complex molecules.
