Abstract

It is shown that the presence of surface contaminant layer exerts influence upon the parameters of ionic bunches from laser plasma formed under interaction of superintense femtosecond laser pulses with solid targets. The usage of pulsed laser pre-cleaning of the targets leads not only to reducing Contaminant ions but also to emerging of additional high-energy component in spectra of bulk ions. We showed that one can control the parameters of ionic bunches from plasma such as maximum and mean ions charge, maximum energy of bulk substance ions by adjusting of the preceding time of the cleaning laser pulse. Thus, using the silicon target and pulses of moderate intensity (2⋅10¹⁶ W/cm²) it is possible to produce the ionic bunches with maximum ions energy of about 400 keV and with a charge state of up to +12.
