Research Abstract

Resonant ionization via two-photon excitation by high-repetition rate, narrow band-width Ti : Sapphire laser was developed for the isotope-selective laser ion source. The feasibility of a Doppler free two-photon spectroscopy inside a hot cavity was demonstrated. The isotope shift and hyperfine structure of the transition from 3s^2 3p^<2 ^3P (J=0, 1, 2) to 3s^2 3p4p^3P (J=0, 1, 2) in silicon could be resolved using a seeded Ti:sapphire laser operating at a repetition rate of 7 kHz. This new method will allow highly pure ion source of not only ultra short lived radio isotopes, but also long-lived radio isotopes.
