  In the framework of the Model of the Stochastic Vacuum elastic hadron-hadron
scattering, photo- and electroproduction of vectormesons and also F_2(Q^2) can
be well described at center of mass energy approximately 20 GeV. The scattering
amplitude is derived by smearing the color dipole-dipole scattering, which is
calculated nonperturbatively in the Model of the Stochastic Vacuum, with
appropriate wavefunctions. For the considered processes the dipoles have
extensions in the range of hadron sizes. We now extend this idea to small
dipoles and high energies. The energy dependence is modeled in a
phenomenological way: we assume that there a two pomerons, the soft- and the
hard-pomeron, each being a simple pole in the complex angular plane. We couple
dipoles of hadronic size to the soft-pomeron and small dipoles to the
hard-pomeron. For small dipoles we take the perturbative gluon exchange into
account. By that way we obtain an energy dependent dipole-dipole scattering
amplitude which can be used for all the processes with the same parameters. We
show that this approach can describe in addition to all the low energy results
(20 GeV) also the HERA data for the considered processes in a large energy and
Q^2 range. Especially the right transition from the soft to the hard behavior
is observed.
