Near-field Ultrafast Nondiffractive Laser Nanoscale Cutting of Glass with Quasi-null Interface Roughness
Rajeev Dwivedi, Anton Rudenko, Guodong Zhang +5
Generally, ultrafast laser glass dicing is governed by explosive material removal, which restricts the achievable surface roughness. Here we report single-step dicing of aluminosil…
Ultrafast laser high-aspect-ratio extreme nanostructuring of glass beyond λ/100
G. Zhang, A. Rudenko, R. Stoian +1
The ultimate feature size is key in ultrafast laser material processing. A capacity to signiicantly exceed optical limits and to structure below 100nm is essential to advance ultra…
Plasma formation and relaxation dynamics in fused silica driven by femtosecond short-wavelength infrared laser pulses
P. Jürgens, M. J. J. Vrakking, R. Stoian +1
Laser-induced plasma formation and subsequent relaxation in solid dielectrics is the precursor to structural modifications that are accompanied by a permanent alteration of materia…
Ultrafast Bessel beams; advanced tools for laser materials processing
Razvan Stoian, Manoj K. Bhuyan, Guodong Zhang +3
Ultrafast Bessel beams demonstrate a significant capacity of structuring transparent materials with high degree of accuracy and exceptional aspect ratio. The ability to localize en…
Ultrafast Surface Plasmonic Switch in Non-Plasmonic Metals
E. Bévillon, J. P. Colombier, V. Recoules +3
We demonstrate that ultrafast carrier excitation can drastically affect electronic structures and induce brief surface plasmonic response in non-plasmonic metals, potentially creat…
First-principles calculations of heat capacities of ultrafast laser-excited electrons in metals
Emile Bévillon, Jean-Philippe Colombier, Vanina Recoules +1
Ultrafast laser excitation can induce fast increases of the electronic subsystem temperature. The subsequent electronic evolutions in terms of band structure and energy distributio…
