Abstract

The phase transition from a superfluid to a Mott insulator has been observed in a 23Na Bose-Einstein condensate. A dye laser detuned 5 nm red of the Na 3 ^2S \rightarrow 3 ^2P_1⁄2 transition was used to form the three dimensional optical lattice. The heating effects of the small detuning as well as the three-body decay processes constrained the timescale of the experiment. Certain lattice detunings were found to induce a large loss of atoms. These loss features were shown to be due to photoassociation of atoms to vibrational levels in the Na2 1 3(Sig)g+ state.
