A model was proposed which accounted for a deformation instability which appeared, during intense laser irradiation, in a system of point defects on the surface of a solid with a high density of sinks. It was shown that the development of this instability, under conditions that were linear with respect to the amplitude, created complex 3-dimensional surface structures (rings, radial arrays, 1-dimensional and 2-dimensional lattices) of coupled strain and defect densities. Dispersion relationships were derived for the growth of these structures, and their characteristic sizes (grating period, number of rays in a structure) were found.
