Definition: the reduction in photon energy in certain processes

German: Stokes-Verschiebung

Category: nonlinear optics

How to cite the article; suggest additional literature


There are various kinds of optical processes where the resulting radiation has a decreased photon energy (or an increased wavelength) compared with the incoming radiation. Such a loss of photon energy is often called Stokes shift, referring to the Irish physicist George G. Stokes. Stokes shifts occur e.g. in the following cases:
