Observation of single Cs atoms in a far detuned optical bottle beam trap

ORAL

Abstract

We report on observation of single Cs atoms in a far detuned optical bottle beam (BoB) trap. The BoB is formed by crossed 532 nm vortex beams which are projected through a single lens. Ground state trapping with a lifetime of several seconds is obtained. We will discuss the prospects for quasi-magic trapping of both ground and Rydberg atoms in the BoB using additional compensation fields.
