Abstract
The mechanism of dislocation photodamping in NaCl with F-centers is investigated by means of simultaneous measurements of the amplitude dependent internal friction and the dislocation charge. The dislocation photodamping is confirmed to arise from light-induced generation of pinning points, and the pinning points nature and conditions of their formation are studied. On the base of the experimental data the model of the dislocation photodamping is proposed.
