Journal ArticleDOI
Ripples revisited: non-classical morphology at the bottom of femtosecond laser ablation craters in transparent dielectrics
TL;DR: In this article, the authors observed a complex structure of fine ripples at the bottom of the ablated crater, which are oriented perpendicular to the beam polarization, and they assumed that the ripples structures are due to self-organization structure formation during the relaxation of the highly nonequilibrium surface after explosive positive ion emission.
Journal ArticleDOI
Sub–damage–threshold femtosecond laser ablation from crystalline Si: surface nanostructures and phase transformation
TL;DR: In this paper, femtosecond laser ablation from crystalline silicon (100) targets placed under ultra-high vacuum was investigated. And the results revealed the formation of periodic structures at the crater bottom.
Journal ArticleDOI
Surface patterning on insulators upon femtosecond laser ablation
TL;DR: In this paper, the crater morphology upon femtosecond laser ablation from BaF2 and CaF2, exhibits several periodic structures of characteristics that cannot be explained by interference phenomena.
Journal ArticleDOI
Self-organized pattern formation upon femtosecond laser ablation by circularly polarized light
TL;DR: In this article, the authors describe an unstable surface layer, non-uniformly eroded through Coulomb repulsion between individual positive charges, which is attributed to self-organized structure formation from instability.
Journal ArticleDOI
Femtosecond laser induced nanostructure formation: self-organization control parameters
TL;DR: In this article, the s-component of the incident field, not attenuated by the projection, determines length and orientation of the ordered ripples, resulting in curved structures bending from polarization-controlled to defect-controlled orientation.
