More or less charged ions of various elements are useful for different applications or for studying purposes. It is generally accepted that Laser Ion Sources are the most effective sources of ions, which are emitted from the laser-produced plasma. Construction of LIS is briefly described. Generation of ions (their charge state, the kinetic energy and amount of them) is influenced by many factors, which are summarized and discussed. The used corpuscular diagnostics are mentioned, too., Leoš Láska, Josef Krása., and Obsahuje bibliografii
