Abstract

Long-range interactions on the 5s5p ³ P 0 -5s4d ³ D 1 transition of Sr was first proposed [1] as the blue-detuned optical lattice allows the interatomic distance one order of magnitude shorter than the transition wavelength. We aim to create such an optical lattice at 412 nm of the magic wavelength in experiment to further study long-range interactions. Here we present the calculation of the atomic polarizabilities for 5s5p ³ P 0 and 5s4d ³ D 1 states. We also characterize the axial frequency on the lattice laser power and beam waist. The 412 nm lattice laser is frequency doubled from a Ti-Sapphire laser. Experimentally characterizing the optical lattice is still ongoing.
