Informationally Complete Orbital Angular Momentum Tomography with Intensity Measurements
M. Gil de Oliveira, A. L. S. Santos Junior, P. M. R. Lima +4
In this work we study the tomography of the spatial structure of light. We develop a simple technique that allows one to perform the tomography over the space of fixed order modes.…
Anomalous Second Harmonic Generation of Twisted Gaussian Schell Model Beams
M. Gil de Oliveira, A. L. S. Santos Junior, A. C. Barbosa +6
We investigate theoretically and experimentally the optical second harmonic generation (SHG) with a twisted Gaussian Schell model (TGSM) beam as the fundamental field. We use Type-…
Trapping microparticles in a structured dark focus
F. Almeida, I. Sousa, O. Kremer +5
We experimentally demonstrate stable trapping and controlled manipulation of silica microspheres in a structured optical beam consisting of a dark focus surrounded by light in all…
Observation of triangular-lattice pattern in nonlinear wave mixing with optical vortices
B. Pinheiro da Silva, G. H. dos Santos, A. G. de Oliveira +8
A triangular-lattice pattern is observed in light beams resulting from the spatial cross modulation between an optical vortex and a triangular shaped beam undergoing parametric int…
