The mechanism of stimulated radial scattering and the specific damages caused by it in the surface layers of optical media, which are most clearly manifested in media with a low threshold of the bree transition phases, are considered. These fractures are the result of plastic deformation of the surface under the action of converging acoustic waves generated by radial scattering. It is shown that stimulated radial scattering can be responsible for laser destruction of interference mirrors, and a mechanism for its excitation in thin layers is proposed.
