The implementation of resonance ionization using powerful tunable laser systems at high transmission mass separators has led to numerous research activities on stable as well as radioactive isotopes. Aside of the application as highly selective and efficient ion source for rare species at radioactive ion beam (RIB) facilities like ISOLDE at CERN or ISAC at TRIUMF, direct in-source spectroscopy on atomic structure and nuclear ground state properties are carried out, e.g., in the range of the actinides and other radioisotopes. At the RISIKO off-line mass separator facility the laser systems are adapted and such investigations are prepared, complementing efficient implantation runs of ultrapure radioisotope samples for specific programs. These include collections of 6Li, 53Mn, 55Fe, 158Tb, 163Ho, and 226Ra in microscopic metallic calorimeters (MMCs) and on other targets. The technology will be presented with special emphasis on the laser systems and the required mass separator optimizations together with some recent applications of relevance.
