“…As a result, the mechanisms and regularities of forming the characteristics of multiply charged ions of a two-element laser plasma in the eld of pulsed laser radiation will be obtained experimentally and theoretically discussed [9][10][11]. In this case, new possibilities can be found for controlling beams of multiply charged ions in a two-element laser plasma in terms of quantity, charge composition, and energy range.…”

The charge, energy, and spatial characteristics of multiply charged ions (hydrogen and nitrogen) of a two and multi-element laser plasma were studied using the laser ionization mass spectrometry method. The targets were made of pure C (i.e. graphite), Cu, polyethylene (CH2)n (consisting of hydrogen atoms (H) in a bound state), Cu[H] (with embedded H atoms) and Ti[H,N], Zr[H,N] (consisting of hydrogen atoms (H) and (N)) in the form of a thick cylinder with a thickness of l = 2 mm and a radius of R = 0.5 cm. It has been experimentally shown that the properties of both light and heavy ions in plasma depend both on the conditions for the entry of gas atoms into the target and on secondary processes occurring after the formation of a dense plasma on the surface of the sample. It has been found that the presence of light gas atoms significantly affects the parameters (for example, intensity and charge multiplicity) of heavier ions.

“…Creating multiply charged high-order ions is possible using ultrashort fs-pulsed laser radiation, which has a low light flux compared to short ns-pulsed laser radiation [14,15]. The time evolution of the formation of multiply charged ions under the action of ns and fs pulsed laser radiation on carbon was studied [16,17].…”

The paper presents the results of a study of the charge and energy characteristics of multiply charged ions excited on the surface of a single-element and hydrogen-containing multi-component element targets under the influence of laser radiation with a power density (q=108-1012 W/cm2). It has been experimentally shown that, for all used values of q laser radiation, laser-induced plasma from gas-containing targets is characterized by a lower relative yield (dN/dE) of multi-charged ions with a charge number of Z>+3, compared to the plasma produced on the surface of the single element target. Moreover, the tendency to reduce dN/dE of multi-charged ions of the multi-element target, in comparison with the relative yield of ions from the plasma of the single-element target, is more significant and it depends on the charge of the excited ions. The increase in the charge and energy state, duration, and yield of ions of the heavy component, which occurs with an increase in the content of the light component in the target, has been established. This is explained by a decrease in the efficiency of recombination processes caused by an increase in the expansion velocity of a plasma plume due to a decrease in its average mass.
