Optically trapped ion Coulomb crystals are an interesting platform for quantum simulations due to the long range of the Coulomb interaction as well as the state dependence of the optical potential. Optical lattices expand the possible application of this platform by trapping the ions in seperate potential wells as well as giving optical confinement along the axis of the beam. In the past we presented the succesfull trapping of a single ion in a one dimensional optical lattice as well as of ion coulomb crystals in a single beam optical dipole trap.
In this Poster, we present recent advancements in trapping of Ba138+ ions in a one dimensional optical lattice at a wavelength of 532nm and report the first successfull trapping of small ion coulomb crystals (N≤3) in this lattice. We compare trapping results between the lattice and a single beam optical dipole trap and investigate the effect of an axial electric field on the trapping probability of a single ion to demonstrate the axial confinement of the ion in the optical lattice.
