Abstract
Using the time-of-flight mass-spectrometer with an electrostatic analyzer, we study the effect of interaction angle of laser radiation θ on the properties of laser-produced plasma ions. It was shown that both the energy, and the charge of the ions are maximum at small angles (θ ≤ 20°), where the absorption of the laser radiation is maximal. With increasing θ from 20° to 70° the intensity of single charged ions increases while the intensity of highly charged ions are not much affected (slightly decreases). Analysis of energy spectra of ions shows that with increasing θ the shape of energy spectra for ions with charge Z ≥ 1 ractically
does not change, although the maximum of the distribution shifts to lower energies.
