Methods for improving characteristics of laser source of ions

In this work we discuss four methods to improve the characteristics of laser source of ions, namely: (i) the effect of the angle of interaction of laser radiation with targets on the plasma ions characteristics, (ii) the use of targets of different densities to improve the parameters of plasma ions, (iii) the influence of laser frequency on the plasma parameters and (iv) the effect of irradiation dose of the target on the emission of multi-charged ions. Our study will be based on the analysis of the mass-charge spectrum of laser-produced plasma ions for different intensities of laser radiation.
