The method consists in focusing a uniformly polarized laser beam onto a uniaxial crystal having its optic axis parallel to the propagation axis of the impinging beam. A simple approximated model is used to obtain the analytical expression of the beam polarization at the output of the crystal. The output beam is then proved to be a FPB. By changing the polarization state of the input field, full-Poincare beams are still obtained, but presenting different distributions of the polarization state across the beam section. Experimental results are reported, showing an excellent agreement with the theoretical predictions. 2040-8978 10.1088/2040-8986/aabdad https://hdl.handle.net/20.500.14352/12166 http://dx.doi.org/10.1088/2040-8986/aabdad http://iopscience.iop.org Synthesis of full Poincare beams by means of uniaxial crystals
