Title:	Development and application of laser technologies at radioactive ion beam facilities
Abstract:	In the last ten years, laser resonance ionization has developed into a mature technique, playing a key role in the production of radioactive nuclides at on-line isotope separator facilities. The technique has advanced and developed to a point where it is the favoured production mechanism for hot cavity ion sources at on-line radioactive ion beam facilities, however for gas catcher target systems the understanding of the underlying processes is far from being complete. During the last four years a laser ion source was installed and commissioned for the IGISOL facility of the University of Jyväskylä, Finland. The fast and universal resonant laser ion source (FURIOS) facility comprises both high-resolution Ti:Sapphire lasers and dye lasers, therefore providing an unparalleled universal coverage of ionization schemes throughout the periodic table. A total of 14 different elements have been studied at this new facility by laser spectroscopy. The challenge to prepare and manipulate pure samples of radioactive isotopes far from stability has required the development of new experimental techniques including optical pumping and in-source spectroscopy. The progress goes hand in hand with the demand for new laser technologies tailored to the specific application. The talk introduces the laser system and presents the first results obtained from off-line and on-line experiments involving laser technologies at the IGISOL facility as well as at facilities based on hot-cavity ion sources.
