| Research Abstract |
Toward novel practical atomic clocks using ion-cooling, state selection, and state detection by ion-atom cold collisions, replacing conventional atomic clocks such as hydrogen masers, we have developed devices for cold atom beam and ion trap, and laser systems for optical pumping of cold Rb beam. As for laser, we have adopted a second-harmonic-generation(SHG) of 795 nm(Rb D1 line) using periodically-poled-lithium-niobate(PPLN) waveguide(WG) device from a 1590 nm DFB laser.
