  We discuss diffractive photon-production of vector mesons in holographic QCD.
At large $\sqrt{s}$, the QCD scattering amplitudes are reduced to the
scattering of pair of dipoles exchanging a closed string or a pomeron. We use
the holographic construction in AdS$_5$ to describe both the intrinsic dipole
distribution in each hadron, and the pomeron exchange. Our results for the
heavy meson photon-production are made explicit and compared to some existing
experiments.
