Nonlinear Optics,
Abstract
The laws of the interaction of high-powered laser radiation with a substance are substantially different from those for light of low intensity generated by ordinary sources. In the field of nonlaser light sources the optical properties of a substance do not ordinarily depend on radiation intensity (the optical characteristics - the refractive index, the degree of absorption and scattering, etc. - remain constant). In this case one speaks of linear optics. If there exists a dependence in the nature of the occurrence of optical effects in solids, liquids, and gases on radiation intensity, one is dealing with nonlinear effects. Eight years of intense development of a new field of physics - nonlinear optics - which appeared after lasers were created has led to a substantial expansion of the knowledge of the interaction of electromagnetic radiation with a substance and the creation of a number of generators spectral devices, and light receivers which are new to optics.
