      A numerical technique is developed to compute a plasma density profile deformation due to a pondero- motive force of a high-frequency electromagnetic radiation under nonstationary conditions in one dimension. The chosen scheme is shown to describe, with a good accuracy (≤3%), available analytic results: Mandelschtamm-Bri1louin forced scattering from a homogeneous plasma layer, stationary solution of a density profile binding problem. Calculational results for density profile deformation are given which indicate the jump instability for pulses greater than 0,1 ns.
