[3H03] Spectroscopic analysis of radioactive strontium with high isotopic selectivity
(1)Laser development and resonance ionization scheme
Keywords:Strontium, Resonance ionization, Isotopic selectivity, Interference filter
Analysis of 90Sr in the marine sample using resonance ionization requires laser excitation of 90Sr atoms with high isotopic selectivity. In this study, we have developed an external cavity diode laser with a narrow bandwidth interference filter for the first-step intercombination transition.
