Enhanced ablation and photoacoustic excitation in near-threshold laser ablation of liquid-coated surfaces [PDF]

open access: yesJournal of Applied Physics, 2001
The effect of an artificially deposited liquid film on a laser-ablated metal surface at near-threshold laser fluences is presented. Experiments utilizing a Q-switched Nd:YAG laser (wavelength=1064 nm, full width at half maximum=6 ns) reveal that deposition of a liquid film results in substantial reduction of ablation threshold and enhancement of ...

The impact of O/Si ratio and hydrogen content on ArF excimer laser ablation of fused silica [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2014
The impact of stoichiometry and hydrogen content on the ArF excimer laser ablation characteristics of fused silica is investigated. Near-surface substoichiometic SiOx with X < 2 diminishes the ablation threshold as a result of increased absorption.

The Experimental and Modeling Study of Femtosecond Laser-Ablated Silicon Surface

open access: yesJournal of Manufacturing and Materials Processing, 2023
In this study, monocrystalline silicon was ablated by a single 1030 nm femtosecond laser pulse. Variable laser fluence (0.16–3.06 J/cm2) was used, and two ablation thresholds (0.8 and 1.67 J/cm2) were determined experimentally.

Atrial fibrillation ablation: is common practice far from guidelines' world? The Italian experience from a national survey

open access: yes, 2022
PURPOSE: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, occurring in 1-2% of the general population. Catheter ablation has become an important treatment modality for patients with symptomatic drug-refractory AF.

Experimental Investigations on Laser Ablation of Aluminum in Sub-Picosecond Regimes

open access: yesApplied Sciences, 2020
Due to high power and ultrashort pulses, femtosecond lasers excel at (but are not limited to) processing materials whose thicknesses are less than 500 microns. Numerous experiments and theoretical analyses testify to the fact that there are solid grounds
