Trapping single Cs atoms in an optical bottle beam

We have implemented a microscopic optical bottle beam (BoB) trap using 532 nm light focused to waists of $w=2$ and $4~\mu\rm m$. We obtain calculated trap depths $>100~\mu\rm K$. The BoB trap has the potential for stable trapping of both ground state and Rydberg atoms. We have superimposed the BoB trap with a Cs magneto-optical trap, and will report progress towards observation of single trapped Cs atoms.
