Abstract.

We review how moderately intense laser fields offer an approach to alignment of molecules [1]. In particular, molecules can be aligned along a given space fixed axis, forced to a plane, or their rotations about all three possible axes can be eliminated by choosing a linearly polarized, a circularly polarized, or an elliptically polarized alignment field, respectively. We show how molecules in the gas phase can be aligned by turning on the laser field either slowly (a few nanoseconds) or fast (a few picoseconds) with respect to the rotational period of the molecules. The role of the intensity of the laser field and the rotational temperature of the molecules is discussed. Before concluding we describe how aligned molecules enables control and selectivity in the interaction between polarized light and molecules.

    The radial distribution is obtained by an angular integration of the 2-dimensional I\(^{2+}\) ion image. It is proportional to the projection of the ion velocity on the detector, which in term, is very close to the full ion velocity because the alignment of the molecules causes the ions to be ejected in the plane of the detectorGoogle Scholar
