We study a tripartite system made up of a two-level atom and two leaky QED (quantum electrodynamical) cavities, prepared in coherentes states in the dispersive regime, generalizing [Phys. Rev. A.59, 3918 (1999)] which examines the interaction of an atom with a single cavity. We consider an experimental setup in which the atom interacts succesively with an inital high-Q cavity, a Ramsey zone and a final high-Q cavity. We compute the dynamical evolution of the total system and the concurrences of the three different two-qubit subsistems, varying the cavity mean-photon numbers and the dissipation rates. The entanglement transfer is different from zero, regardless the dissipation rate or the average photon number, unless the flight time is large as compared to the photon lifetime or it is equal to very specific instants of time.

In this paper we studied the main conditions for the Plasmas generation air, copper and aluminum, using a laser Nd: YAG pulsed with wavelength 1064 nm with a pulse of 500 mJ Energy and 9 ns duration at a repetition rate of 10 Hz. Through spectroscopy, we have analyzed Optical Emission lines Spectral emission, which were obtained by varying the Atmospheric pressure. Emissivity to High pressure is greater because of the confinement of the plasma and Increasing collisions between different species, in the case Plasma in the air we compared the data obtained from each Wavelength due to each transition and electronic state of Ionization with wavelengths characteristic of each Element reported by the database of the NIST (National Institute of Standards and Technology).

The Fresnel zone plates are described suitably with the help of the classic theory of the diffraction; in this particular case when a plane wave illuminates a certain type of bicomponent optical system, consisting of plane screens with circular apertures on a given optical axis, a multifocal diffractive focusing effect can appear; this configuration allows to obtain small regions with much intensity, here the diffraction picture in the focal planes represents the circular nonlocal bands of the Fresnel zones with a bright narrow peak at the center. In this article a detailed description of the working principle of the Fresnel zone plates and general equation for the Fresnel zonal plate diffraction is derived within the framework of the fractional Fourier transform.

This work shows the characterization for polarized Light microscopic of a sets of samples from Coveñas, Moñitos, Los Cordobas, San Bernardo del viento and San Antero beaches. The results indicate that the first three beaches are rich in quartz and fedelpast, while the San Bernardo's beach is composed basically for minerals concerning to the group of the Pyroxene, in addition to, the San Antero's beaches that are rich in minerals of the group of the Calcite, furthermore, in it's found a high content of organic impurities. The morphologic, morphometric and morphoscopi of the samples also were studied. The determinations of the minerals constitute the different beaches that can be important for future technological and researching applications. [ABSTRACT FROM AUTHOR]

In this work we study the optical properties of the ternary compound CuInSe2 and CuGaSe2 using the DFT and FP-LAPW method. These materials are important to have applications in non lineal optics in the construction of infrared detectors and solar cells polycrystalline based on thin films of high efficiency and low cost where are used like active layer. Therefore, it is important to know so much theoretical as experimentally their optic properties (complex dielectric tensor, complex refraction index and absorption coefficient).

Using the macroscopic formalism of the Kerr Effect, the magneto-optical (MO) response of (Cox/Pdx)n and (Cox/Ptx)n multilayers was simulated while varying x (monolayer thickness) and n its periodicity . Later the MO response of the same multilayers was simulated with Pd and Pt cov-ers. With the variation of those parameters the MO effects Faraday-Kerr transition (TF-K) is ob-served. It is shown a TF-K surface as a function of those parameters. [ABSTRACT FROM AUTHOR]

a retrospective is made, where it is shown that the ondulatory mechanics elements World be insinuated by William Hamilton in the XIX century. He obtained a set of equations from the unifying of optical and dynamics laws, that could be used to describe the wave movement and the particle one. From his findings, it is deduced equal that the light rays are substituted by the concept of waves in optics, the particle trajectories must be substituted by ondulatory movement in mechanics.

The behavior of a flowing viscoelástico Maxwelliano is studied through a Porous media one (MP). In first instance the solution of the problem of the flow of Poiseuille is presented for a flowing stationary newtoniano using a group of capillary tubes as MP, finding the permeability of the MP. Later is solved the problem for a flowing dependent Maxwelliano of the time through a MP, generalizing the permeability concept to the dynamic case and analyzing the behavior of the dynamic permeability in function of the frequency, that which will allow to analyze the human heart frecuency from this optics.

A preliminary study of the reflected light spectrum of coffee berries in different stages of development was made, in order to get spectral information for the design of Automatic Artificial Vision Systems with color response, applicable to the coffee agroindustry. In this work, the normalized spectrum of the light reflected by coffee fruits of different ripeness stages are presented, observing typically that the unripe fruits spectrum present maximum peaks between 560 nm and 610 nm, and the ripe ones between 610 nm and 650 nm. On the other hand, it was observed that the unripe and ripening berries presented fluorescence in the neighborhood of 685 nm, whereas the ripe, overripe and dry ones did not. [ABSTRACT FROM AUTHOR]

The study of the nature of the polarized light, has allowed the development of classical and modern theories of great interest, in the technological systems, in addition to being able to study other phenomena from the states of polarization of the light. In this work the notation due to P. A. Dirac for the description of the polarization states is used, showing the analogies with the electromagnetic theory, and the obtaining of the parameters of Stokes and its relations with the correlation matrix, with the aim to establish the important relations between polarization and coherence. An experimental procedure sets out to establish these correspondences and some of its implications, in addition to a form to generate mutually exclusives states in a same system and the results of the variation of the coherence within this.

The equilateral hyperbolic zone plates (EHZP) of fixed and variable focal length, who exhibit cross focal shaped pattern, are elements used in far distance transversal detection systems, among others. Nevertheless, the shape that can be achieve with this diffractive systems, is affected by the out of focus produced when data is taken from planes at distances different to the focal distance, In this work we study how the focal pattern of a fixed focal length EHZP varies and how the precision in the measure of the displacement is affected, in planes close to the focal length of the EHPZ. With this we pretend to determine the out of focus sensibility of this elements. [ABSTRACT FROM AUTHOR]

The circularly symmetric Laguerre Gaussian (L-G) laser modes have generated great interest in recent years because they possess an orbital angular momentum of ihl per photon in addition to the spin angular momentum associated to the polarization state of the beam, where part of the experimental efforts have focused to obtaining them. In this work, we have used the Fourier optics formalism to describe an optics system known as "π/2 astigmatic mode converter" a practical method of getting L-G laser modes from the more usual Hermite Gaussian (H-G) laser modes. The system consists in two aligned cylindrical lenses with opposite orientations, and we also have simulated the effect of the converter over an H-G laser mode (m = 1, n = 0), (m = 0, n = 1) having the lens as Fourier transformed, obtaining functional relations whose intensity pattern seem like those corresponding L-G.

In this report we developed software that it adds primary optical aberrations to imported images by user. The software funtionality is achieved by means of the implementation of the library JAI (Java Advanced Imaging). The program's operation is simple and visually nice. The user chooses the percentages of participation of aberrations that will accompany the original image and equally the user could improve the quality of original image by mean of the modification of shine and contrast. From optical view point, the software simulates a lens with choosed aberrations that it operates on imported image, taken as the object, and it can to deliver images around the best focus plane. The aberrations are induced by by the addition of phases wi th definied shapes (these phases can be visualized by the user), to the phase of the imported image. An online tutorial has been constructed about the software's operation and the optical aberrations theory from the diffraction. [ABSTRACT FROM AUTHOR]
