Summary on Grant Application Form |
|
The optical manipulation of molecules requires new schemes of coherent manipulation to overcome the complications introduced by their rovibrational level structure. Broadband interactions are needed to access multiple levels, and spontaneous emission must be minimized to reduce population migration. Starting with atomic rubidium in a magneto-optical trap, and progressing to photo-associated rubidium molecules, we shall explore various schemes of coherent manipulation, including deflection, amplification of Doppler cooling, interferometric cooling and 'algorithmic' cooling using our proposed momentum-state quantum computer. The optical manipulation is in each case is achieved via stimulated Raman transitions using a phasecontrollable modulated c.w. laser source. These experimental studies will complement on-going theoretical analyses, and will ultimately be combined with advanced dipole-force trap geometries. This research thus explores a broad range of novel manipulation schemes that will allow the advantages of laser cooling and trapping to be extended to molecules of scientific and technological interest. The ultimate applications range from fundamental physics and reaction chemistry, to directed chemical synthesis, nanofabrication and quantum information.
