Influence of structure defects in Al target on efficiency of the multi charge ions production in laser plasma

Interaction of the intensive laser radiation (λ- 1,06 μm) with a irradiated solid body has been studied. Investigations were carried out by collector and time- flight mass-spectrometry methods both. A joint analysis of electron and ion currents, as well as of charge, energy parameters of multicharged ions of the plasma produced in the irradiated and initial targets, allows us to state that the preliminary irradiation of the target by the flux of 1015-1019 neutrons per cm2 stimulates the production of high temperature plasma.
