RT Journal Article T1 Beam quality of partially polarized beams propagating through lenslike birefringent elements A1 Piquero Sanz, Gemma María A1 Movilla Serrano, Jesús María A1 Mejías Arias, Pedro Miguel A1 Martínez Herrero, María Rosario AB 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.
