The authors thank J. Serna for his valuable suggestions in the course of reading the manuscript.A procedure for global beam shaping by modifying some global spatial parameters characteristic of the beam is proposed. This method is based on the generation of a nonuniformly polarized beam using a Mach-Zehnder system with two suitably shaped intensity transmittances and orthogonal linear polarizers. The changes in beam quality and kurtosis parameters after a linear polarizer placed at the output of the system are investigated.engjournal articlehttp://dx.doi.org/10.1364/AO.45.008902http://www.sciencedirect.comhttp://www.opticsinfobase.org/open access535Laser-BeamOptical-SystemsPhase PlatesQualityDesignLensLawsÓptica (Física)2209.19 Óptica Física
