The excitation of X-ray plasma satellites was investigated in the plasma created by subpicosecond laser pulses with various intensities. It is shown that when laser flux density is greater then 6x10{sup 16} W/cm{sup 2} strong oscillating electrical fields with {omega}{approx}(1.5-1.6)x10{sup 15} s{sup -1} are excited in the plasma. These oscillations lead to modifications of profiles of X-Ray spectral lines observed.
