Schematic of the simultaneous formation of LIPSS and DLIP structures. (a) DLIP pattern on the surface. White represents intensity maxima and the red arrows the direction of the polarization. (b) Absorbed light intensity on the surface taking into account surface plasmon polariton excitation. (c) Hot (red) and cold (blue) areas resulting from absorption of light intensity pattern shown in (b). White arrows indicate the expected direction of the material flow. (d) Surface relief after resulting from the movement in (c). White indicates pronounced parts of the surface.
