Addressing Single Sites Of A CO2-Laser Optical Lattice

Abstract

To conclude, we have optically resolved an optical lattice based on the infrared radiation of a CO2-laser operating near 10.6 μm. This type of optical lattice has exciting prospects for quantum logic experiments. In addition our 1-D geometry minimises reabsorption of spontaneously emitted photons. This could allow for the possibility of reaching Bose-Einstein condensation by optical cooling alone.

We resolve and address atoms in single sites of an optical lattice with a period of 5.3 µm created by a retroreflected, focused CO 2 laser beam. In this one-dimensional lattice, the Lamb-Dicke limit can be fulfilled in all three spatial dimensions. Because of the negligible decoherence rate from spontaneous photon scattering such a lattice offers unique possibilities for the study of quantum phenomena in a controllable environment.

Abstract We report on experiments with all‐optically produced Bose‐Einstein condensates in a mesoscopic optical lattice. By retroreflecting the radiation of a CO2‐laser operating near 10.6 μm, a lattice with spacing between sites of λ /2 ≃ 5.3 μm is realized, for which atom tunneling is negligible. Once cooled to quantum degeneracy by direct evaporative cooling in the lattice, the properties of the trapped microclouds can be studied with far field interference experiments. The microscopic atom clouds are shown to be in the two‐dimensional regime for small atom filling. The realized system has extremely long coherence times, and holds fascinating prospects for both quantum logic and the study of novel collective phenomena.

Resolving and addressing atoms in individual sites of a CO2 -laser optical lattice

We report on the microscopic imaging of individual sites of an optical lattice with a period of 5.3 \ensuremath{\mu}m created by a retroreflected, focused ${\mathrm{CO}}_{2}$-laser beam. In this one-dimensional lattice, the Lamb-Dicke limit is fulfilled in all three spatial dimensions. Single lattice sites have been individually addressed with a focused near-resonant laser beam. Because of the negligible decoherence rate from spontaneous photon scattering such a lattice holds intriguing prospects for the realization of fault-tolerant quantum logic gates.
