Evaluation of biomimetic coatings on femtosecond laser treated alumina and alumina-zirconia composite surfaces
(2016-01-01)
The effect of texturing Al2O3 and Al2O3/ZrO2 surfaces using femtosecond laser has been evaluated in terms of the roughness, wettability and microstructure of the substrate to increase growth efficiency and adhesion of ...
Influence of effective number of pulses on the morphological structure of teeth and bovine femur after femtosecond laser ablation
(SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERSBELLINGHAM, 2012)
Femtosecond lasers have been widely used in laser surgery as an instrument for contact-free tissue removal of hard dental, restorative materials, and osseous tissues, complementing conventional drilling or cutting tools. ...

Femtosecond laser fabrication of waveguides in DR13-doped PMMA
(Elsevier BVAmsterdam, 2014-05)
This work demonstrated the fabrication of tubular waveguides in bulk samples of PMMA doped with Disperse Red 13 (DR13) by oscillator only fs-laser micromachining. We studied the influence of the incident pulse energy on ...
MATFESA: Strain and refractive index field estimation after femtosecond laser interaction with transparent material
(Springer Heidelberg, 2013-03)
In this paper we present the development of an open code ("MATFESA") based on the Finite Element Method (FEM) which can be used to estimate the strain and refractive index fields after femtosecond laser writing process by ...
Design and implementation of an integrated optical coupler by femtosecond laser written-waveguides in LiNbO3
(Elsevier, 2020-03)
This work presents a particular application corresponding to waveguides manufactured by the femtosecond laser micro-machining technique. More specifically we have conducted the study, design, simulation and implementation ...
Evidence of 5-aminolevulinic acid (ALA) penetration increase due to microdrilling in soft tissue using femtosecond laser ablation
(SPRINGER LONDON LTDLONDON, 2012)
Photodynamic therapy (PDT) is a therapeutic technique mainly applied to the treatment of malignant and pre-malignant lesions, which induces cell death by the combined effect of a photosensitizer, irradiation in a proper ...
Characterization and Stability of Silver Nanoparticles in Starch Solution Obtained by Femtosecond Laser Ablation and Salt Reduction
(American Chemical Society, 2017-05)
Silver nanoparticles (Ag NPs) colloids obtained by femtosecond laser ablation in soluble starch (st) solution and silver salt reduction methods were characterized using optical extinction spectroscopy, micro-Raman spectroscopy, ...
