Optimal beam displacement measurements using high-order structured light modes
A. L. S. Santos Junior, J. C. de Carvalho Junior, M. Gil de Oliveira +4
We develop a novel technique to measure small angular and lateral displacements of structured light beams. The technique relies on using high-order Hermite-Gaussian (HG) and Laguer…
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-…
