Phys. Rev. Lett. 94, 203001 (2005) [4 pages]Optical Production of Ultracold Polar MoleculesReceived 29 December 2004; published 23 May 2005 We demonstrate the production of ultracold polar RbCs molecules in their vibronic ground state, via photoassociation of laser-cooled atoms followed by a laser-stimulated state transfer process. The resulting sample of X1Σ+(v=0) molecules has a translational temperature of ∼100 μK and a narrow distribution of rotational states. With the method described here it should be possible to produce samples even colder in all degrees of freedom, as well as other bialkali species. © 2005 The American Physical Society URL:
