Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Optical Society of America | 2003-03From a theoretical point of view, the use of anisotropic pure-phase plates (APP) is considered in order to improve the quality parameter of certain partially coherent, partially polarized beams. It is shown that, to optimize the beam-quality par[...]texto impreso
Serna Galán, Julio ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | The Optical Society Of America | 1993-03-01The beam quality behavior of Hermite-Gauss laser modes propagating through Gaussian apertures is analyzed.texto impreso
Serna Galán, Julio ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Optical Society of America | 1992-08-01Beam quality behavior of Gaussian Schell-model beams that propagate through Gaussian apertures is analyzed.texto impreso
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Elsevier Science BV | 2008-02-15In terms of the so-called irradiance moments of a light field, the beam quality change, ?Q, of radially and azimuthally polarized beams caused by propagation through a quartic phase plate (as occurs for example, in strongly pumped laser rods us[...]texto impreso
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Kluwer Academic Publishers | 1995-03The effects that quartic phase distortions generate in tridimensional beam quality parameters of laser fields are investigated. Two cases of special interest are considered: a rationally symmetric spherically aberrated lens, and a pair of identi[...]texto impreso
Serna Galán, Julio ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Taylor and Francis Ltd. | 1992-03The quality behaviour of Gaussian Schell-model fields propagating through general (non-orthogonal) ABCD optical systems has been characterized by introducing a number of parameters. Such parameters have been given in terms of the Wigner distribu[...]texto impreso
Serna Galán, Julio ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Chapman & Hall Ltd. | 1992-09An analytic and measurable beam parameter is defined for beams emerging from heterojunction monomode diode lasers with very thin active layers, which provides a joint description of their focusing capabilities and far field divergence behaviour.[...]texto impreso
Piquero Sanz, Gemma María ; Movilla Serrano, Jesús María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Optical Society of America | 1999-11Changes 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-orde[...]texto impreso
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | SPIE--The International Society for Optical Engineering | 2006Several overall parameters are introduced to characterize the linear or circular polarization content of a non-uniformly totally polarized beam over the region of its wavefront where the irradiance is significant. These parameters are determined[...]texto impreso
Piquero Sanz, Gemma María ; Movilla Serrano, Jesús María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Kluwer Academic Publishers | 1999-03Two overall parameters are proposed to characterize the degree of polarization and its uniformity across the transversal section of non-uniformly partially polarized beams. Such parameters can be measured according to the well-known standard met[...]texto impreso
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | SPIE--The International Society for Optical Engineering | 2002The behaviour of the so-called generalized degree of polarization of partially-coherent partially-polarized beams upon free propagation is investigated. On the basis of this parameter a general classification scheme of partially polarized beams [...]texto impreso
Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Gustav Fischer Verlag | 1997-03The behaviour of thin pure phase transmittances is represented by means of a generalized matrix, M, which can be handled as the ABCD-matrices associated with ordinary first-order optical systems. This formalism enables the application of general[...]texto impreso
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel ; Ramírez Sánchez, Victoria | Elsevier Science BV | 2008-04-15Several global parameters are proposed to characterize the radial and azimuthal polarization content of non-uniformly totally polarized beams. Such figures of merit can be written and measured in terms of two Stokes parameters, and also from the[...]texto impreso
Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Gustav Fischer Verlag | 1999Explicit easy-to-compute expressions have been derived for the transmitted amplitude of a Fabry-Perot electrooptic modulator which take into account the influence that various surface deformations exert on the output response of the system. Thre[...]texto impreso
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | The Optical Society Of America | 1992-06-01A Procedure for obtaining linear (one-dimensional) Gaussian intensity distributions over certain plane regions is proposed. The method is based on the reflection of plane beams on elliptic cylinders.
