Nonlinear optics

Physics portal

Here is a list of articles in the Nonlinear optics category of the Physics portal. Nonlinear optics is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization P responds nonlinearly to the electric field E of the light. This nonlinearity is typically only observed at very high light intensities such as provided by pulsed lasers.
