ABSTRACT
We demonstrate experimentally an enhancement in Raman scattering in Rb atomic vapor due to the atomic coherence initially prepared by a weak write laser. We find that the enhanced Raman scattering depends on the spatial distribution of the atomic spin coherence and can be explained with a simple picture of three-wave mixing. This effect can in principle be used to have a light conversion efficiency near unity in Raman process. Such an enhanced Raman scattering may have practical applications in quantum information, nonlinear optics, and laser spectroscopy.

    Quantum control over molecular alignment rephasing is experimentally investigated in gaseous CO[sub 2]. The control process is achieved by illuminating the medium with a pair of pump-pulses separated in time by approximately an integer value of T[sub 0]=1/8B[sub 0], where B[sub 0] is the...

    We report on the relationship between material disorder and nonlinear optical response for a conjugated polymer. Inverse Raman scattering, the technique used here, is sensitive to the transition cross sections of both the purely electronic (Sv=01Sv=00) and vibronic (Sv=01Sv=10) transitions...
