Mechanism of suprawavelength microstructures formation on metal surfaces by linear polarized ultrashort laser radiation

The model for suprawavelength structures formation based on the experimental data of nano- and microrelief of metal surface evolution under linear polarized laser radiation and on the nonlinear mathematical model of ordered spatial periods formation was suggested. The model is based taking into account the mutual interference of surface plasmon polaritons propagating in neighbouring directions and is applicable for oxidizing metals.
