Abstract
We have observed that the efficiency of second-harmonic generation from a monolayer of chiral molecules depends on the handedness of the incoming fundamental beam. This circular-difference effect is observed both in reflection and transmission of the second-harmonic radiation. Analogous to linear optical activity, we show that these effects can be explained by including contributions of magnetic-dipole transitions to the second-order nonlinear susceptibility.
