Radial-angular coupling in self phase modulation with structured light
M. Gil de Oliveira, L. J. Pereira, A. S. Santos +3
In this work we study the evolution of an optical vortex undergoing self phase modulation inside a nonlinear Kerr medium. The intensity dependent phase evolution couples the angula…

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-…
