Cavity Cooling of internal and external degrees of freedom of molecules. — •Giovanna Morigi1, Pepijn Pinkse2, Markus Kowalewski3, and Regina de Vivie-Riedle3 — 1Departament de Fisica, Universitat Autonoma de Barcelona, E-08193 Bellaterra, Spain — 2Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Str. 1, 85748 Garching — 3LMU Department Chemie, Butenandt-Str. 11, 81377 München
A proposal is presented for effectively cooling vibrational, rotational, and translational degrees of freedom of molecules. The molecules are driven by off-resonant laser light and cooled through Raman processes, where photons are scattered into the resonator, which then decays into free space. Photon emission occurs at a multitude of cavity resonances in a suitably designed resonator. The cooling efficiency is investigated numerically for the case of the OH radical, using ab-initio data and taking into account the rovibrational dependence of the Raman scattering into the cavity modes. Extentions to more complex molecules will be considered.
