    The emission of Fe ions and ionized admixtures of silicon, carbon, oxygen and hydrogen generated by a Nd:YAG laser (I ≈ 1x10^10 W/cm^2) is investigated with the use of ion collectors (IC) and a cylindrical electrostatic ion mass analyzer (CEA). The partial currents of ion species are reconstructed from a set of CEA spectra obtained by changing the voltage between the CEA's cylindrical deflecting plates. The basic difference between the sum of all the reconstructed partial currents and the corresponding IC current is analyzed and the reasons for differences are specified.
