Paper Abstract

The regular structure formation on a silicon surface under the millisecond pulse of linear-polarized Nd-laser light irradiation has been studied experimentally. The surface structures induced by the interference of incident wave and surface electromagnetic waves and also the double-period structures with periods d — 2-3 microns were observed in the nonhomogeneous melting regime. The double-period structures formation was explained by polaritonic mechanism and was due to a nonlinear absorptance changes in semiconductor-metal phase transition.
