Nonlinear polarization spectroscopy, a new type of laser spectroscopy of solids, is used for the investigation of cubic crystals with reorienting centers. This technique based on the self‐induced change of light polarization (SICLP) is applied for the determination of fine parameters of F A (Li)‐, F A (Na)‐, F 2 ‐centers in KCl. It is shown that the mechanism of phonon‐induced mixing of wave‐functions belonging to nondegenerate and degenerate excited electronic states of F A ‐centers is responsible for SICLP manifestation in KCl with F A ‐centers.
