The formation of nearly wavelength-sized laser-induced periodic surface structures (LIPSSs) on single-crystalline silicon upon irradiation with single or multiple femtosecond-laser pulses (pulse duration τ=130 fs and central wavelength λ=800 nm) in air is studied experimentally and theoretically. In our theoretical approach, we model the LIPSS formation by combining the generally accepted first-principles theory of Sipe and co-workers with a Drude model in order to account for transient intrapulse changes in the optical properties of the material due to the excitation of a dense electron-hole plasma. Our results are capable to explain quantitatively the spatial periods of the LIPSSs being somewhat smaller than the laser wavelength, their orientation perpendicular to the laser beam polarization, and their characteristic fluence dependence. Moreover, evidence is presented that surface plasmon polaritons play a dominant role during the initial stage of near-wavelength-sized periodic surface structures in fem...read more

Ultrafast Dynamics of Sub-Wavelength Periodic Surface Structuring during Femtosecond Laser Processing of Dielectrics
TL;DR: In this paper, the effects of laser fluence on sub-wavelength periodic surface structuring based on ultrafast laser electron dynamics control was investigated, and a quantum model for the periodic surface structure was proposed, which considers both wave properties in the photon particle-properties based plasma model for photon-electron interactions and transient localized changes of material properties.
