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
In this contribution we study the relation between the second order intensity moments and the Goos-Hanchen shift for partially coherent totally polarized beams. The results are applied to a type of partially coherent beams, the Cosine-Gaussian S[...]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.texto impreso
Maluenda, David ; Juvells, Ignasi ; Martínez Herrero, Rosario ; Carnicer, Artur | Optical Society American | 2019-05-15Optical needles produced by means of diffractive technology might display limited quality and uniformity. It has been suggested that the bulky optical elements present on these setups can be responsible of such behavior. In particular, issues su[...]texto impreso
Maluenda, David ; Carnicer, Artur ; Jubells, Ignasi ; Martínez Herrero, Rosario | Spie-Int Soc Optical Engineering | 2017In this communication we analyze the light field distribution of a highly focused radially polarized beam when passes through a linear polarizer. The polarizer is modeled as a plane-parallel uniaxial absorbing medium with the optical axis parall[...]texto impreso
Martínez Herrero, Rosario ; Jubells, Ignasi ; Maluenda, David ; Carnicer, Artur | Spie-Int Soc Optical Engineering | 2019In the present communication, we describe how to produce long light distributions in the focal area of a high numerical aperture optical system using a custom modulation function with spiral charge. This analysis expands our previous development[...]texto impreso
Piquero Sanz, Gemma María ; Movilla Serrano, Jesús María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Kluwer Academic Publishers | 2000-12On the basis of well-known methods to obtain the standard Stokes parameters, two simple experimental procedures are analysed to measure the so-called generalized degree of polarization, P, defined elsewhere [Opt. Commun., 149 (1998) 230]. After [...]texto impreso
Serna Galán, Julio ; Martínez, C. ; Encinas Sanz, Fernando ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Elsevier Science B.V. | 1997-07-01From the application of a simple analytical model to describe a laser pulse, the transversal spatial structure of the pulse amplitude is linked to its (measurable) second-order intensity moments, integrated along the pulse duration. These formul[...]texto impreso
Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Elsevier Science BV | 1995-03-15The behaviour of the kurtosis parameter of a partially coherent beam that freely propagates is investigated. A general classification scheme of light beams is given in terms of the number of extremals of the kurtosis in free space. Propagation t[...]texto impreso
Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Elsevier Science BV | 2006-09-01Several 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 figures of merit are dete[...]texto impreso
Serna Galán, Julio ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | The Optical Society Of America | 1991-07Within the formalism of the Wigner distribution function, a new parameter is proposed, which characterizes arbitrary tridimensional partially coherent beams and is invariant through ABCD optical systems. The relationship between such a parameter[...]texto impreso
Serna Galán, Julio ; Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Chapman & Hall Ltd. | 1996-08The influence of super-Gaussian apertures on the beam power, beam size, beam quality factor and kurtosis parameter of Hermite-Gauss mode beams and Gauss Schell-model fields is investigated in detail.texto impreso
Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | SPIE - International Society of Optical Engineering | 1996As is well-known, pure-phase transmittances are not, in general, first-order optical systems. It thus seems that a simple ABCD-propagation law cannot be applied to this kind of transmittance. In other words, such optical elements could not be ch[...]texto impreso
Piquero Sanz, Gemma María ; Movilla Serrano, Jesús María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Elsevier Science BV | 1998-04-15A new overall parameter is defined, namely, the generalized degree of polarization, which involves the spatial distribution of the polarization of a light beam. This parameter is introduced on the basis of a general treatment recently proposed [[...]
