Nonlinear optics refers to the study of light-matter interactions in which intensity-dependent changes in the interactions occur. Among the effects studied in nonlinear optics are intensity-dependent frequency changes, intensity-dependent polarization changes, intensity-dependent beam sizes, intensity-dependent amplitude changes, and intensity dependent phase changes. The following sections describe more in depth the origins of nonlinear optics, and what makes nonlinear optics different from linear optics.
