JOSA A, vol. 16, n.o 11, noviembre de 1999, pp. 2666-68. opg.optica.org, https://doi.org/10.1364/JOSAA.16.002666.0740-323210.1364/JOSAA.16.002666https://hdl.handle.net/20.500.14352/58835This work was supported by the Comisión Interministerial de Ciencia y Tecnología of Spain under project PB97-0295.Changes generated by lenslike birefringent elements on the beam-quality parameter of partially polarized beams are investigated. Analytical expressions for the beam-quality gain at the output of such systems are given in terms of the second-order intensity moments of the field. Explicit conditions to improve and optimize the beam-quality parameter after propagation through these birefringent transmittances are also shown.engjournal articlehttp://dx.doi.org/10.1364/JOSAA.16.002666http://www.opticsinfobase.org/open access535Optical-SystemsLawsÓptica (Física)2209.19 Óptica Física
