Inhomogeneous Broadening

Inhomogeneous broadening is an increase of the Linewidth of an atomic transition caused by effects which act differently on different radiating or absorbing atoms. This can be caused e.g. by the different velocities of the atoms of a gas, or by different lattice locations of atoms in a solid medium. Inhomogeneous broadening is strongly related to Inhomogeneous Saturation in Laser Gain media.
