In this work we estimate the differential cross section for the high energy deeply virtual Compton scattering on a photon target, {gamma}*{gamma}{yields}{gamma}{gamma}, within the QCD dipole-dipole scattering formalism. For the phenomenology, a saturation model for the dipole-dipole cross section for two photon scattering is considered. Its robustness is supported by a good description of current accelerator data. In addition, we consider the related exclusive vector meson production processes, {gamma}*{gamma}{yields}V{gamma}. This analysis is focused on the light {rho} and {phi} meson production, which produces larger cross sections. The phenomenological results are compared with the theoretical calculation using the color-dipole Balitsky-Fadin-Kuraev-Lipatov approach.
