Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Sande, J.C.G de ; Santarsiero, Massimo | Optical Society of America | 2020-04-01Polarization of a light beam is traditionally studied under the hypothesis that the state of polarization is uniform across the transverse section of the beam. In such a case, if the paraxial approximation is also assumed, the propagation of the[...]texto impreso
Martínez Herrero, Rosario ; Maluenda, David ; Carnicer, Artur | Nature Publishing Group | 2018-02-08We introduce a new method for producing optical needles with tunable length and almost constant irradiance based on the evaluation of the on-axis power content of the light distribution at the focal area. According to theoretical considerations,[...]texto impreso
Serna Galán, Julio ; Encinas Sanz, Fernando ; Martínez Herrero, Rosario ; Martin Mejías, Pedro | Optical Society of America | 2001-07The evolution of the intensity profile of transversely excited atmospheric CO_2 laser pulses is investigated within the intensity moment formalism. The beam quality factor M_2 is used to study the mode evolution. Attention is focused on the infl[...]texto impreso
Serna Galán, Julio ; Martínez, C. ; Encinas Sanz, Fernando ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | IEEE-Inst Electrical Electronics Engineers Inc. | 1998-10The time evolution of the transversal modes in a TEA CO_2 laser cavity has been investigated from the analysis of the time-varying beam quality factor M^2 of the emitted pulses. The experiments reveal a significant change in this parameter durin[...]texto impreso
Martínez Herrero, Rosario ; Carnicer, Artur ; Juvells, Ignasi ; Sanz Ortiz, Ángel Santiago | The Optical Society Of America | 2020-09-29In the analysis of the on-axis intensity for a highly focused optical field, it is highly desirable to deal with effective relations aimed at characterizing the field behavior in a rather simple fashion. Here, a novel and adequate measure for th[...]texto impreso
Martínez Herrero, Rosario ; Maluenda, David ; Piquero Sanz, Gemma María ; González de Sande, Juan Carlos | IEEE | 2016In this work a physically realizable pseudo Schell-model planar light source with optical vortex is proposed. The characteristics of irradiance and coherence of the beam radiated by this type of source are analysed at the source plane and upon f[...]
