| 英文摘要 | we investigate the role of surface nanoscale topographies in the inhomogeneous coupling of laser radiation to ni-based superalloy cmsx-4 surfaces and in the formation of laser-induced periodic surface structures. the initial surface arbitrary roughness is already able, upon laser exposure, to induce low-spatial-frequency and high-spatial-frequency structures, actively determining an interference of incoming and scattered fields resulting in spatial energy modulation. a topology variation with the incoming dose via the number of pulses determines a correlated evolution in the regular ripple arrangements. the scattering pattern is severely influenced by the scattering source geometries. therefore, we equally study experimentally the role of one-dimensional nanoscale grooves in determining polarization-dependent structuring patterns at increasing irradiation dose. finally, the role of surface nanostructures in generating the surface modulation of deposited energy is analyzed by finite-difference-time-domain simulation. ripple formation in multi-pulses is a result of the feedback process between light and nanostructures. |
