Abstract

Second-harmonic generation from chiral surfaces has different responses to fundamental beams that are left- and right-hand circularly polarized. This form of nonlinear optical activity can occur within the electric-dipole approximation. However, second-order nonlinearities involving magnetic-dipole transitions, which can be strong in chiral media, also contibute to the circular-difference response. We describe a new measurement technique that is based on continuous variation of the state of polarization of the incoming fundamental field, which allows us to assess the relative importance of the electric- and magnetic-dipole contributions to the circular-difference response. We will report the results of our measurements on second- harmonic generation from surfaces consisting of thin films of chiral polymers.
