Based on the color dipole representation, we investigate consequences for the γ*γ*,γ*γ scattering of the finding by Fadin, Kuraev and Lipatov that incorporation of asymptotic freedom into the BFKL equation makes the QCD pomeron a series of isolated poles in the angular momentum plane. We present parameter-free predictions for the vacuum exchange contribution to the photon structure function which agree well with OPAL and L3 determinations. A good agreement is found between our predictions for the energy and photon virtuality dependence of the photon-photon cross section σγ^*γ^*(W,Q2,P2) and the recent data taken by the L3 Collaboration.
