Abstract
We have used second-harmonic generation as a technique to examine different types of chiral materials. All materials investigated showed large circular-difference effects in the second-harmonic response, i.e., the efficiency of the process was different for left- and right-hand circularly-polarized light. Study of various chiral materials has shown that a different quantitative and qualitative response can be expected depending on the composition and structure. In addition, we have demonstrated the existence of magnetic-dipole coniributions to the nonlinearity of those materials.
