Full textLaguerre-Gaussian modes of light are one of the solutions to the propagation equation of light in the paraxial approximation in cylindrical coordinates. These modes are characterized by two indices (azimuthal and radial) and present particular properties: ring-shaped structure and a helical phase. These properties have been put to use in several applications going from microscopy to astronomy. This work has been devoted to the study of these modes and their application in the cold atom domain. Initially, the purity of such modes generated by numerical holography was studied, as well as the role played by the purity in their propagation. These modes were then used to obtain a bright source of cold atoms. For more than 20 years, considerable efforts have been made to create sources of cold atoms as bright and compact as possible. A two dimensional magneto-optical trap (2D-MOT) is currently used to obtain a continuous source of cold atoms with high flux of the order of 1010 atomes/s. Nevertheless, the source of cold atoms thereby achieved show a divergence of about 40 mrad which constrains the user to work by output but with a limited optical access or far from the output but at the cost of lower density. An alternative is presented, in which a Laguerre-Gaussian mode of light is used to channel the atoms at the output of a 2D-MOT. The Laguerre-Gaussian mode of light carries out a dipole trapping that confines the atoms in the black center of the mode, which has the advantage of limiting the heating due to absorption/emission of light. Thus, since the Laguerre-Gaussian modes of light keep their ring-shape along their propagation, the atoms are channeled over a distance of several decimeters. We studied the functioning of this system for different orders of the Laguerre-Gaussian mode and at different frequencies, and we showed that this system is efficient and allows to achieve a density gain of a factor 200 compared to a conventional 2D-MOT. A particular case is also presented, in which the frequency of the Laguerre-Gaussian mode of light is chosen to carry out not only the channeling of the atoms, but also their repumping, which leads to an important simplification of the system. Laguerre-Gaussian modes of light are also of great interest in the domain of quantum information and quantum cryptography because they can be used to encode and store information. In order to do that, it is crucial to be able to detect them in an unequivocal way. In this context, we are interested in the determination of these modes. Until now, different detection techniques have measured the azimuthal index, but few of them have been able to measure the radial index. If we are able to measure the radial index, it can be used as a new variable to encode and store information. Under this motivation, a technique based on the transformation of a Laguerre-Gaussian mode of light by an astigmatic system has been extended to determine the two indices characterizing them. We showed that this technique can also be used to experimentally optimize the generation of the purest possible Laguerre-Gaussian modes of high order

In this work we present a classification of the Laguerre minimal surfaces with flat curvature lines. We introduce three classes of hypersurfaces that generalize the Laguerre minimal surfaces with the prescribed Gaussian normal application. The first class is associated to biharmonic applications and is related by a Legendre transformation to hypersurfaces that in the isotropic model has harmonic isotropic mean curvature. As an application, we classify the hypersurfaces of rotation and we present examples of these hypersurfaces parameterized by flat curvature lines. We obtain a characterization of the other two classes of hypersurfaces, we study the rotation ones and we present examples.
Neste trabalho apresentamos uma classificação das superfícies mínimas de Laguerre com linhas de curvatura planas. Introduzimos três classes de hipersuperfícies que generalizam as superfícies mínimas de Laguerre com aplicação normal de Gauss prescrita. A primeira classe está associada a aplicações biharmônicas e está relacionada por uma transformação de Legendre a hipersuperfícies que no modelo isotrópico tem curvatura média isotrópica harmônica. Como aplicação, classificamos as hipersuperfícies de rotação e apresentamos exemplos destas hipersuperfícies parametrizadas por linhas de curvatura planas. Obtemos uma caracterização das outras duas classes de hipersuperfícies, estudamos as de rotação e apresentamos exemplos.

Full textThis work focuses on the design, realization and experimental study of highly coherent dual-frequency laser sources emitting at 1 µm for THz radiation generation by photomixing. We are particularly interested in vertical-external-cavity surface-emitting laser (VeCSEL), the aim being to obtain a robust dual-frequency continuous wave operation, based on simultaneous coexistence of two Laguerre-Gaussian transverse modes. We design intracavity transverse selective losses mask to select only the two Laguerre-Gaussian modes. The stable and simultaneous dual-frequency operation, the beat-frequency tunability range and the temporal coherence was specifically studied. We demonstrated THz emission by seeding a uni-travelling-carrier photodiode by an optically-pumped dual-frequency vertical-external-cavity surface-emitting
