Abstract
We have produced large samples of ultracold Sr molecules in the electronic ground state in an optical lattice. The molecules are bound by 0.05 cm and are stable for several milliseconds. The fast, all-optical method of molecule creation via intercombination line photoassociation relies on a near-unity Franck-Condon factor. The detection uses a weakly bound vibrational level corresponding to a very large dimer. This is the first of two steps needed to create Sr in the absolute ground quantum state. Lattice-trapped Sr is of interest to frequency metrology and ultracold chemistry.
