Description
We present the first experimental realization of Bragg diffraction for polar and non-polar molecules [1]. Using a thick laser grating at 532 nm, we diffract a molecular beam and observe Bragg diffraction in the far-field. We study this effect for the dye molecule phthalocyanine and the antibiotic ciprofloxacin and observe a pronounced angular dependence and asymmetry in the pattern, characteristic for Bragg diffraction. We can thus realize an effective mirror and a large-momentum molecular beamsplitter with a momentum transfer of up to 18 grating photon momenta. This is an important step towards gaining control over the manipulation of functional, complex molecules.
