- In this work, two new types of structured light beams are introduced: the vortex Pearcey-Gauss (VPeG) beam, with homogeneous polarization, and the vector vortex Pearcey-Gauss (VVPeG) beam, featuring non-homogeneous, non-separable polarization. Scalar Pearcey-Gauss beams were generated using a spatial light modulator, while vortex and vector vortex beams were created using a q-plate with circular and linear polarization, respectively. Their intensity and polarization evolution along propagation were characterized using Stokes polarimetry and compared with simulations. The VVPeG beam transforms from linear to near full-Poincaré polarization, enriching the family of non-separable states with promising applications in optical metrology and tweezers.
