We perform one- and two-photon high resolution spectroscopy on ultracold samples of RbCs Feshbach molecules with the aim to identify a suitable route for efficient ground-state transfer in the quantum-gas regime to produce quantum gases of dipolar RbCs ground-state molecules. One-photon loss spectroscopy allows us to probe deeply bound rovibrational levels of the mixed excited (A(1)Σ(+)-b(3)Π)0(+) molecular states. Two-photon dark state spectroscopy connects the initial Feshbach state to the…

The RbSr 2Σ+ ground state investigated via spectroscopy of hot and ultracold molecules.

A mass-scaled high-precision model for X(1)2Σ+ by fitting all data using a single fit procedure, which is consistent with all data, thus spanning short-to-long internuclear distances and bridging an energy gap of about 75% of the potential well depth, still uncharted by any experiment.

Singlet Pathway to the Ground State of Ultracold Polar Molecules.

A two-photon pathway to the dipolar ground state of bi-alkali molecules that involves only singlet-to-singlet optical transitions and an ideal three level system is established, even if the hyperfine structure is not resolved.

Continuous formation of vibronic ground state RbCs molecules via photoassociation

We demonstrate the direct formation of vibronic ground state RbCs molecules by photoassociation of ultracold atoms followed by radiative stabilization. The photoassociation proceeds through deeply

Production of ultracold 85Rb133Cs molecules in the lowest ground state via the B1Π1 short-range state.

The B1Π1 (v = 3) state is found to have the maximum production rate for ground-state molecules with a value of 3(1) × 104 s-1, which is 3 times larger than the value via the previously studied 23Π0+ ( v = 10, J = 0) state with two-photon cascade decay.
