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-…

Resonance of Vector Vortex Beams in a Triangular Optical Cavity
L. M. Rodrigues, L. Marques Fagundes, D. C. Salles +5
We experimentally demonstrate resonance of first-order vector vortex beams (VVB) with a triangular optical cavity. We also show that, due to their symmetry properties, the VVBs com…

Partial coherence and coherence length in StimPDC
Gustavo Henrique dos Santos, Raphael César Souza Pimenta, Rafael de Morais Gomes +2
In parametric down conversion, a nonlinear crystal is pumped by a laser and spontaneous emission takes place in signal and idler modes according to the phase matching conditions. A…
