Anti-vortices with a hyperbolic polarization structure and radially polarized vortices are demonstrated. They exist close to and partially coexist with vortices with uniform and non-uniform polarization distributions characterized by four domains of pairwise orthogonal polarization. These vector vortices are argued to have soliton-like properties. Independently of this interpretation, the novel way of generating these nontrivial structures in a remarkably simple VCSEL system is regarded to be interesting and potentially beneficial for other experiments utilizing non-uniform polarization structures. %G English %2 https://hal.science/hal-01631138/document %2 https://hal.science/hal-01631138/file/Jimenez_Garcia_etal_PRL_2017_Spontaneous_formation_of_vector_vortex_beams_in_vertical_cavity_surface_emitting_lasers.pdf %L hal-01631138 %U https://hal.science/hal-01631138 %~ CNRS %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
