Title: Steady-state modification of the electron density profile in the resonance region of moving plasma subjected to an alternating electric field

Self-consistent electron density profiles of the plasma stream interacting with the electric field of an ultrashort laser pulse are calculated in the framework of the one-dimensional steady-state model with nonlocal polarizability. These profiles are settled down against the background of a given (linear) ion density distribution as a result of the equilibrium between the averaged ponderomotive force, the static space-charge field, and the electron pressure. The average electron density and the longitudinal (parallel to the density gradient) ac electric field are found to be greatly space-modulated in the region downstream of the plasma resonance point.
