Dual behavior of caustic optical beams facing obstacles
(American Physical Society, 2017-06)
A full propagation analysis on both fold-type and cusp-type caustic optical beams under various setups of obstructions is theoretically and experimentally performed. It is demonstrated that the self-healing property of ...
Nonsymmetric curved beams within a symmetric caustic skeleton
(Optical Society of America, 2018-09)
Nonsymmetric curved beams having a symmetric caustic skeleton are presented. They arise from a finite jump in the symmetric spectral phase that breaks the symmetry of the beam intensity without altering its associated ...
Mechanical and microstructural characterization of laser-welded joints of 6013-T4 aluminum alloy
(Springer, 2015-01-01)
Laser beam welding may be used in the place of the traditional riveting process for the welding of the stringers to the skin in aircrafts. This work intends to investigate the mechanical behavior of laser-welded aluminum ...
Sistema automatizado para gravação de estruturas fotônicas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2017-11-22)
An automated system is reported in this work with the goal of fabricating photonic structures by the direct-write technique with femtosecond laser pulses. This technique uses a finely focused laser beam into transparent ...
Low-cost system for micrometer-resolution solar cell characterization by light beam-induced current mapping
(IOP Publishing, 2014-10)
Light-beam induced current (LBIC) mapping is an increasingly utilized characterization technique for laboratory-scale as well as industrial-scale solar cells, which measures the local solar cell photocurrent by point ...
Optical beam deflection sensor: Design and experiments
(2017-10-01)
In this work, we present a double-pass optical beam deflection sensor and its optical design method. To accomplish that, a mathematical model was proposed and computational simulations were performed, in order to obtain ...
