In the field of atom-light interaction, laser resonance ionization mass spectrometry has developed into one of the most versatile techniques, especially for investigations on exotic species, i.e. rare radionuclides.  This concerns similarly selective ionization and atomic spectroscopy of artificially produced species at on-line mass separator facilities as well as ultra trace determination in analytics.  Remarkable achievements in both fields are due to the appearance of state-of-the art laser systems ensuring outstanding efficiency, selectivity and low detection limits of the method.  An overview on status and recent activities in this domain with specially emphasizing the use of modern solid state laser systems for laser ion source developments at on-line facilities and for analytical purposes is given.
