An optical elevator for precise delivery of cold atoms using an acousto-optical deflector

Abstract We implement a simple method for fast and precise delivery of ultracold atoms to microscopic device, i.e. Fabry–Perot microcavity. By moving single beam optical dipole trap in direction perpendicular the axis with an acousto-optical deflector, we transport up 1 million within 100 ms over cm. Under these conditions, efficiency above 95% is achieved only minimal heating. The atomic cloud accurately positioned microcavity transferred into intra-cavity lattice. With addition secondary guiding beam, show how residual sloshing motion along shallow can be minimized.
