Abstract

A theory which explains self-consistently the emission and the polarization rotation of transmitted light has been developed forF A centres in crystals with cubic symmetry. Azimuthal dependences ofF A luminescence in alkali halides are very informative for determining the electron-phonon interaction as well as the parameters related to the structural and optical quality for coulour centre lasers crystals. The theoretical results are applied to the interpretation of the luminescence properties ofF A (Li) centres in KCl, RbCl and KF.
