Journal ArticleDOI
The effect of damage accumulation behaviour on ablation thresholds and damage morphology in ultrafast laser micro-machining of common metals in air
TL;DR: In this paper, the ablation threshold fluence depends on the number of pulses applied to the same spot, and the strength of this dependence is governed by the incubation coefficient, S, which has been determined along with the single-shot threshold, φ th (1), for all the metals studied.
Journal ArticleDOI
Characterisation of an antibody coated microcantilever as a potential immuno-based biosensor
C. M. Grogan,Roberto Raiteri,Gerard M. O'Connor,Thomas J. Glynn,V Cunningham,Marian Kane,M Charlton,Dónal Leech +7 more
TL;DR: Preliminary experimental results showing the antibody activity against myoglobin, detected with a microcantilever based sensor prototype confirmed the motivations and potentialities of the proposed immunosensing technique.
Proceedings ArticleDOI
Ablation thresholds in ultrafast laser micromachining of common metals in air
TL;DR: In this article, the authors studied the ablation of metal targets in air with femtosecond laser pulses, and showed that the intensity of the laser pulses depends logarithmically on the optical penetration depth.
Journal ArticleDOI
Quantitative analysis of cocaine in solid mixtures using Raman spectroscopy and chemometric methods
TL;DR: In this article, the authors used Raman spectra from a series of 33 solid mixtures containing cocaine, caffeine and glucose (9.8-80.6% by weight cocaine), which were then analyzed using chemometric methods.
Journal ArticleDOI
The mechanism of nanobump formation in femtosecond pulse laser nanostructuring of thin metal films
Dmitriy S. Ivanov,Baerbel Rethfeld,Gerard M. O'Connor,Thomas J. Glynn,Alexey Volkov,Leonid V. Zhigilei +5 more
TL;DR: In this article, the physical mechanisms responsible for the formation of nanobump structures on a surface of a thin metal film irradiated by a tightly focused femtosecond laser pulse are investigated in a large-scale molecular dynamics simulation.
