Shen, Y R

Second-order nonlinear optical effects have recently been proven to be an extremely versatile analytical tool for surface studies. They are forbidden in media with centrosymmetry and hence, highly surface specific. Being coherent optical techniques, they have high temporal, spatial, and spectral resolution, and are useful for experiments requiring in-situ probing and remote sensing. They also have the advantage of being applicable to any interface accessible by light. In these lectures, we shall give a general review on the development of such techniques. We first present the underlying theory of a second-order optical process at an interface. We then discuss, with examples, the various possible applications of second harmonic and sum-frequency generation for surface studies. 57 refs., 16 figs.
