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 6×1016W/cm2 strong oscillating electrical fields with ?~(1.5-1.6)×10 15s-1 are excited in the plasma. These oscillations lead to modifications of profiles of X-Ray spectral lines observed.

Abstract
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 6×1016W/cm2 strong oscillating electrical fields with ?~(1.5-1.6)×10 15s-1 are excited in the plasma. These oscillations lead to modifications of profiles of X-Ray spectral lines observed.File in questo prodotto:
