Quantum control by stimulated Raman scattering

In a model system, i.e. the K2 dimer molecule, a vibrationally excited wave packet around a prechosen target state in the electronic ground state is generated by an ultrafast resonant stimulated Raman process. By choosing the pump and dump wavelengths along the difference potential between the excited electronic |B〉-state and the electronic ground state |X〉 and optimizing the delay time between the pump and dump processes, one can increase considerably the efficiency of the population transfer of this quantum control experiment.
