Spin to orbital angular momentum transfer in nonlinear wave mixing
B. Pinheiro da Silva, W. T. Buono, L. J. Pereira +3
We demonstrate the spin to orbital angular momentum transfer in the nonlinear mixing of structured light beams. A vector vortex is coupled to a circularly polarized Gaussian beam i…

Astigmatic tomography of orbital angular momentum superpositions
B. Pinheiro da Silva, D. S. Tasca, E. F. Galvão +1
We use astigmatic transformations to characterize two-dimensional superpositions of Orbital Angular Momentum (OAM) states in laser beams. We propose two methods for doing this, bot…
