Piquero Sanz, Gemma María ; Mejías López, Jesús Ángel ; Martínez Herrero, Rosario ; Movilla Serrano, Jesús María | Pergamon-Elsevier Sciance Ltd | 2002We present an approach for describing the spatial structure of partially polarized light fields. Unlike the treatments usually encountered in the literature, in which the polarization state is represented by position-dependent functions, the for[...]![]()

González de Sande, Juan Carlos ; Martínez Herrero, Rosario ; Piquero Sanz, Gemma María ; Maluenda, David | Scitepress | 2017A new model of physically realizable electromagnetic source is proposed. The source is partially coherent and non-uniformly totally polarized. The coherence and polarization characteristics of this new source are analyzed. The spatial coherence [...]![]()

Santarsiero, Massimo ; Martínez Herrero, Rosario ; Maluenda, David ; González de Sande, J.C. ; Piquero Sanz, Gemma María ; Gori, F. | Optical Soc Amer | 2017-04-15A new class of partially coherent light sources is introduced. At the source plane, they exhibit perfect coherence along any annulus that is concentric to the source center. Between two points at different distances from the center, coherence ca[...]![]()

Martínez Herrero, Rosario ; Maluenda, David ; Piquero Sanz, Gemma María ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco | Spie-Int Soc Optical Engineering | 2017In this work a new type of partially polarized and partially coherent sources is proposed. The coherence characteristics of these sources are dependent on the difference of the radial distances from the source center of the two points to be comp[...]![]()

Martínez Herrero, Rosario ; Maluenda, David ; Juvells, Ignasi ; Carnicer, Artur | Nature Publishing Group | 2017-02-13Polarisers are one of the most widely used devices in optical set-ups. They are commonly used with paraxial beams that propagate in the normal direction of the polariser plane. Nevertheless, the conventional projection character of these devices[...]![]()

Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Elsevier Science BV | 1996-08-15The propagation laws of the intensity moments of a laser beam through ABCD optical systems are generalized to include pure phase transmittances. This is done by representing the behaviour of such transmittances by means of a 4 x 4 matrix, hi, wh[...]![]()

Sande, J.C,G. de ; Martínez Herrero, Rosario ; Piquero Sanz, Gemma María ; Santarsiero, Massimo ; Gori, Franco | Optical Society of America | 2019-02-18Partially coherent pseudo-Schell model sources are introduced and analyzed. They present radial symmetry and coherence characteristics depending on the difference between the radial distances of two points from the source center. As a consequenc[...]![]()

Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario ; Bernabeu Martínez, Eusebio | American Physical Society | 1986-03A novel type of optical bistable configuration, namely the so-called double-ring (DR) device, is presented. The stationary solutions in the purely absorptive case for a homogeneously broadened atomic system are derived. In the mean-field limit i[...]![]()

Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Elsevier Science BV | 1994-02-15The beam quality parameter of gaussian fields propagating through axicons is investigated. A simple analytical formula is derived for the output quality parameter in terms of the input beam width, refractive index of the axicon material and the [...]![]()

Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | SPIE--The International Society for Optical Engineering | 2003Use of anisotropic pure phase plates to improve the quality parameter of certain partially coherent and partially polarized beams is investigated. Analytical expressions for the beam quality after propagation through these anisotropic transmitta[...]![]()

Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | The Optical Society of America (OSA) | 1992-12-01The effects that quartic phase distortions produce in the beam-quality parameter of partially coherent symmetric-intensity beams are studied. An analytical expression for the beam-quality parameter at the output plane of a pure phase plate with [...]![]()

Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Elsevier Science BV | 1994-04-15Sharpness changes of the spatial profile of a gaussian beam induced by spherically aberrated lenses are investigated in terms of the so-called kurtosis parameter. It is shown both theoretically and experimentally that, after a single aberrated l[...]![]()

Encinas Sanz, Fernando ; Serna Galán, Julio ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario ; Martínez, C. | Chapman & Hall Ltd. | 1997-09A simple analytical model is proposed to describe the transversal spatial structure of a tridimensional rotationally symmetric pulsed beam. The spatial behaviour of the pulse amplitude is shown to be linked to its (measurable) second- and higher[...]
