Determination of transition frequencies in a single ${}^{138}$Ba${}^{+}$ ion

Abstract

Transition frequencies between low-lying energy levels in a single trapped ${}^{138}$Ba${}^{+}$ ion have been measured with laser spectroscopy referenced to an optical frequency comb. By extracting the frequencies of one-photon and two-photon components of the line shape using an eight-level optical Bloch model, we achieved 0.1 MHz accuracy for the 5d ${}^2$D${}_{3/2}$ - 6p ${}^2$P${}_{1/2}$ and 6s ${}^2$S${}_{1/2}$ - 5d ${}^2$D${}_{3/2}$ transition frequencies, and 0.2 MHz for the 6s ${}^2$S${}_{1/2}$ - 6p ${}^2$P${}_{1/2}$ transition frequency.
