Thermomechanical ablation under plasmonic field excited by ultrashort laser pulse. Part II

Electrodynamic modeling of running SPP (surface plasmon-polaritons) and interference of the SPP wave with the beam 2 are presented in Part I of our work. Standing wave with alternating hot (antinodes) and cold (nodes) intervals appears thank to the interference. Electrodynamic simulations provide distribution of absorbed energy along the hot and cold intervals, which is utilized in this Part II. Here we discuss how can the ultrafast spatially alternating heating be imprinted into the periodic shape perturbations of a thin film atop a substrate. The Kretschmann's configuration (Kc) and additional (relative to Kc) laser beam #2 for periodic ripples of the film is used. (paper)
