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…

Pulse duration dependence of material response in ultrafast laser-induced surface-penetrating nanovoids in fused silica
Guodong Zhang, Na Li, Hao Zhang +7
The focused ultrafast laser, with its ability to initiate nonlinear absorption in transparent materials, has emerged as one of the most effective approaches for micro-nano processi…

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…
