  Transport properties of the ionic component of dense plasmas are investigated
on the basis of effective potentials taking into account the presence of an
external alternating electrical (laser) field. The latter generates single
particle oscillations of electrons and significantly changes the screening of
the test charge in plasma. Therefore, transport coefficients become
non-monotonic function of the oscillation frequency. The results for the
diffusion and viscosity coefficients are presented. These transport
coefficients are computed using the generalized Coulomb logarithm within the
Chapman-Enskog model for the fluid description. It was revealed that the
oscillation of the electrons in the alternating external field in the
significant reduction of the ionic diffusion and viscosity coefficients. The
ionic diffusion and viscosity coefficients are larger compared to the case
without the external field impact.
