Ground State Laser Cooling Beyond the Lamb – Dicke Limit
– We propose a laser cooling scheme that allows to cool a single atom confined in a harmonic potential to the trap ground state |0〉. The scheme assumes strong confinement, where the oscillation frequency in the trap is larger than the effective spontaneous decay width, but is not restricted to the Lamb–Dicke limit, i.e. the size of the trap ground state can be larger than the optical wavelength...
متن کاملLaser Cooling of two trapped ions: Sideband cooling beyond the Lamb–Dicke limit
We study laser cooling of two ions that are trapped in a harmonic potential and interact by Coulomb repulsion. Sideband cooling in the Lamb–Dicke regime is shown to work analogously to sideband cooling of a single ion. Outside the Lamb–Dicke regime, the incommensurable frequencies of the two vibrational modes result in a quasi-continuous energy spectrum that significantly alters the cooling dyn...
متن کاملMotional Ground State Cooling Outside the Lamb-Dicke Regime
We report Raman sideband cooling of a single sodium atom to its three-dimensional motional ground state in an optical tweezer. Despite a large Lamb-Dicke parameter, high initial temperature, and large differential light shifts between the excited state and the ground state, we achieve a ground state population of 81(4)% after 100 ms of cooling, for the 85% of atoms that survive cooling and re-i...
متن کاملPreparation of Schrödinger cat states with cold ions beyond the Lamb-Dicke limit
A scheme for preparing Schrödinger cat (SC) states is proposed beyond the Lamb-Dicke limit in a Raman-Λ-type configuration. It is shown that SC states can be obtained more efficiently with our scheme than with the former ones. PACS numbers: 42.50.Vk,03.65.-w,32.80.Pi Typeset using REVTEX ∗Electronic address: [email protected] 1 In recent years the system of cold ions moving in a harmon...
