The present paper elucidates the physical mechanism that accounts for the principal/primary stages of the structuring process taking place upon irradiation of a conductive solid with multiple identical femtosecond laser pulses, based on the consideration of a hybrid theoretical model. Heat transfer along with hydrodynamics simulations demonstrate that it is possible to create morphology change conditions by solely exploiting capillary effects, in the absence of either non-thermal melting or evaporation. Simulation results, confirmed by experiments, reveal the intermediate surface modification stage acting as a predecessor of microcones formation.
