Abstract

The extension of known polariton model of laser-induced condensed matter damage followed by ordered structures formation for the case of ultrashort pulse durations and condensed matter of different physical properties was made. In addition to the usual cases of linear or circular polarizations of laser radiation the case of axi-symmetric polarization was theoretically considered and illustrated by experiments with dielectrics, semiconductors and metals. The special case of radially polarized laser radiation is distinguished as one for which laser-produced dynamic resonant the additional energy of excited surface polaritons into diffraction size focal spot. The advantages of axi-symmetrically polarized laser radiation for materials treatment in framework of universal polariton model were discussed. In experiments the wide variety of spatial periods of microstructures were observed which do not described by existing theories. The nonlinear mathematical model which describes the spatial periods of laser-produced microstructures was suggested. Model describes the formation of microstructures with periods multiplied by laser wavelength and predicts the spatial period’s values less than diffraction limit one. The nonlinear theoretical model is illustrated by published experimental data. The idea to explain the cause of the formation of regular nanostructures with anomalous orientation on condensed matter surfaces was suggested. It is based on the effect of wedge (channel) surface plasmon polaritons excitation and their mutual interference under the action of polarized laser radiation. The new phenomenon of laser-induced anisotropy of metal recrystallization under the action of nanosecond duration repetitive pulses of linear polarized radiation was experimentally discovered. The phenomenon was explained as a result of grain-boundary movement by directed flux of skin-layer electrons dragged by surface plasmon polaritons.
