Abstract
Second-order nonlinear optical processes are forbidden in a medium with inversion symmetry They are, however, allowed on surfaces because the surface layers of atoms or molecules are always noncentrosymmetric. As a result, the second-order effects generated from the surface can often dominate those from the bulk. They can then be used as sensitive probes for surface studies.
