Stimulated Parametric Down-Conversion: From Foundational Coherence to Structured Light Applications
M. F. Z. Arruda, M. G. Damaceno, G. H. dos Santos +4
Stimulated parametric down-conversion (StimPDC) is the seeded version of the process that underlies much of photonic quantum information. Replacing the vacuum at one input port wit…
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…
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…
Evaluation of Twisted Gaussian Schell Model beams produced with phase randomized coherent fields
Gustavo Cañas, Esteban Sepúlveda Gómes, Gustavo Henrique dos Santos +6
The twisted Gaussian Schell Model describes a family of partially coherent beams that present several interesting characteristics, and as such have attracted attention in classical…
