The start and evolution of the formation of laser-induced periodic surface structures (LIPSS, ripples) are investigated. The important role of irradiation dose (fluence×number of pulses) for the properties of the generated structures is demonstrated. It is shown how, with an increasing dose, the structures evolve from random surface modification to regular(More)
We report on the structural investigation of self-organized periodic microstructures (ripples) generated in Si(100) targets after multishot irradiation by approximately 100-fs to 800-nm laser pulses at intensities near the single shot ablation threshold. Inspection by surface sensitive microscopy, e.g., atomic force microscopy (AFM) or scanning electron(More)
To shed light on nanopattern formation upon femtosecond laser ablation, an adopted surface erosion model is developed, based on the description for ion beam sputtering. In particular, the dependence of generated patterns on the laser polarization is taken into account. We find that an asymmetry in deposition and dissipation of incident laser energy results(More)
