Homogeneous Broadening

Definition: the increase in the linewidth of an atomic transition caused by effects which affect different radiating or absorbing atoms in the same way

German: homogene Verbreiterung

Category: physical foundations

How to cite the article; suggest additional literature

Homogeneous broadening, as opposed to inhomogeneous broadening, refers to effects which increase the optical linewidth of an electronic transition by equally affecting different radiating or absorbing atoms, ions or molecules. The spectral shape of the transition cross sections of all involved atoms are then equal.

Some common cases with homogeneous broadening are as follows:

Homogeneous broadening is strongly related to homogeneous saturation in laser gain media.
