We develop a novel interferometric technique to measure small angular and lateral displacements of an optical beam. The technique relies on the metrological performance of the Hermite-Gaussian $HG_{m,0}$ spatial modes. We report an improvement factor

In this work we study, both theoretically and experimentally, the tomography of the spatial structure of light. We consider a a spatially structured light mode that is specified by coefficients with respect to some basis, such as the Laguerre-Gaussia

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 angular and radial degrees of freedom of the input vortex, giving rise to a

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-II phase matching and analyze the cross spectral density (CSD) of the
