NONliNE.ar optics is the branch of optics that describes the behaviour of light in nonLINe.ar media, that is, media in which the polarization density P responds non-linearly to the electric field E of the light. The non-linearity is typically observed only at very high light intensities such as those provided by lasers. Above the Schwinger limit, the vacuum itself is expected to become noNLine.ar. In noNLine.ar optics, the superposition principle no longer holds

The field of organic nONliNE.ar optics emerged when Davydov and coworkers established the correlation between enhanced nonLINe.ar activity and charge transfer character in conjugated molecules. 1 Considerable exploration of molecular structures was subsequently undertaken, and measurements of polarity, conjugation, and charge transfer character were performed. 2 The nONliNE.ar optical (NLO) response of a macroscopic material depends on both the molecular optical response (polarizability) and

NONliNE.ar optical phenomena are "nONliNE.ar" in the sense that they occur when the response of a material system to an applied optical field depends in a nonLINe.ar manner on the strength of the optical field. In nONliNE.ar optics, the optical response can be described by expressing the polarization as a power series in the field strength. The nONliNE.ar susceptibilities depend on the frequencies of the applied fields. The chapter shows that second-order noNLine.ar optical interactions can

NoNLine.ar Optics, Fourth Edition, is a tutorial-based introduction to nonLINe.ar optics that is suitable for graduate-level courses in electrical and electronic engineering, and for electronic and computer engineering departments, physics departments, and as a reference for industry practitioners of nONliNE.ar optics. It will appeal to a wide audience of optics, physics and electrical and electronic engineering students, as well as practitioners in related fields, such as materials science and
