The ac Stark shifts of the terahertz clock transitions of barium

doi:10.1088/1674-1056/24/10/103201

Abstract

Wavelength-dependent AC Stark shifts and magic wavelengths of the terahertz clock transitions between the metastable triplet states 6s5d ³D₁ and 6s5d ³D₂ are investigated with considering the optical lattice trapping of barium atoms with the linearly polarized laser. The trap depths and the slopes of light shift difference with distinct magic wavelengths of the optical lattices are also discussed in detail. Several potentially suitable working points for the optical lattice trapping laser are recommended and selected from these magic wavelengths.

Keywords: AC Stark shift optical lattice terahertz clock magic wavelength
