Imágenes 2D de alta resolución micromaquinadas con láseres de nanosegundosHighresolution 2d imagesmicromachined with nanosecond laser
(Asociación Física Argentina, 2014-09)
A fin de posibilitar el micromaquinado láser de distintas imágenes 2D sobre sustratos de silicio, se diseñó un Sistema Automático por Software que permite en líneas generales: analizar y procesar digitalmente en tiempo ...
Key kinematic parameters in low-loss power splitter written by femtosecond laser micromachining
(IOP Publishing, 2018-02)
In this work we design, fabricate and characterize a 1x2 Y-branch powersplitter based on simplied coherent coupling. This device was constructed by type II waveguide structures inscribed by direct femtosecond laser writing ...
Determination of femtosecond ablation thresholds by using laser ablation induced photoacoustics (LAIP)
(Springer, 2013-03)
Femtosecond laser material processing as micromachining and nanoparticles fabrication require a careful control of the fluences deposited on the samples. In many cases, best results are obtained by using fluences slightly ...

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 ...
Microfabricação de guias ópticos em vidros óxidos de metais pesados contendo terras-raras
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-03-23)
In this study, we present the production and characterization of a novel binary glass
system: (100-x)SbPO4-xGeO2 where x = 30, 40, 50, 60, 70, 80 and 90 mol %. The
dependence of GeO2 content on thermal, structural and ...
