Abstract
The results of a detailed study of the ion emission from Al target irradiated with a high-intensity (up to 5 · 1016 W/cm2)1−ps Nd: glass laser pulse are presented. The ion emission measurements were based on the time-of-flight method. An electrostatic ion energy analyzer and ion collectors were employed. The maximum ion energy of about 132 keV and fully striped Al ions were registered. The ion current density of 3 mA/cm2 was measured at the distance of 1 m in the direction of the target normal. Both the measured ion charge distribution and the angular distribution of ion emission are discussed. The dependencies of the parameters of ions emitted from the plasma on the laser-pulse energy as well as on the location of the focus of the laser beam with respect to the target surface were also established.
