The linear dynamical response of the valence electrons of Na2 is investigated using time-dependent local density approximation with frozen ionic positions. We focus on the dipole response in two kinds of laser field with polarizing direction parallel or perpendicular to the connective line between two atoms. The results show that there is a strong anisotropy in the response of Na2.
