Laser Beam Shaping XX.
We introduce and generate the partially coherent non{canonical vortex beams and study their characteristics. The characterization of these fields by means of its intensity is difficult due to the random fluctuations in space and time of partially coh

In this work, we present an introduction to the field of spatially partial coherent beams, while keeping in mind the transverse structure of an optical field. We look closely at the concept of spatial coherence and show some strategies to deal with i

We report on the study and generation of Ince–Gaussian beams in the spatially partially coherent regime. The inherent random fluctuations both in time and space of these partially coherent fields make their characterization difficult. Our results s

A means to digitally generate a partially coherent beam with orbital angular momentum is presented. Our approach is based on encoding the randomness of broadband light passing through a spiral phase plate in a spatial light modulator. We illustrate t

A means to measure orbital angular momentum in a partially coherent beam is demonstrated by using a wavefront folding interferometer. This interferometer allows us to study the cross correlation function of a partially coherent vortex beam. It is sho

An alternative method to experimentally measure the topological charge of a vortex beam is presented. The method is based on the number of polarization singularities arising in the superposition of two off-axis Laguerre-Gauss beams having orthogona

We present an experimental technique to generate partially coherent vortex beams with an arbitrary azimuthal index using only a spatial light modulator. Our approach is based on digitally simulating the intrinsic randomness of broadband light passing

We study the dynamics of polarization singularities in the superposition of two off-axis optical vortices with orthogonal polarization states. The motion of C points, states of circular polarization, is described by varying parameters such as separat
