Phys. Rev. Lett. 100, 233003 (2008) [4 pages]Coherent Transients in the Femtosecond Photoassociation of Ultracold MoleculesReceived 11 December 2007; published 13 June 2008 We demonstrate the photoassociation of ultracold rubidium dimers using coherent femtosecond pulses. Starting from a cloud of ultracold rubidium atoms, electronically excited rubidium molecules are formed with shaped photoassociation pump pulses. The excited state molecules are projected with a time-delayed probe pulse onto molecular ion states which are detected in a mass spectrometer. Coherent transient oscillations of the excited state population are observed in the wings of the pump pulse, in agreement with the time-dependent solution of the Schrödinger equation of the excitation process. © 2008 The American Physical Society URL:
