Schlosser, Nicolas. „Etude et réalisation de micro-pièges dipolaires optiques pour atomes neutres“. Phd thesis, Université Paris Sud - Paris XI, 2001. http://tel.archives-ouvertes.fr/tel-00001195.
Der volle Inhalt der Quellel'implémentation de portes logiques quantiques. Dans ce contexte, cette étude
porte sur la réalisation d'un piège dipolaire optique de si petite taille qu'il
ne puisse contenir qu'un atome unique. Pour cela, il est nécessaire de
focaliser très fortement un laser à l'endroit où l'on désire capturer les
atomes. L'expérience s'articule donc autour d'un objectif de microscope de
grande ouverture numérique, entièrement conçu et réalisé au laboratoire. Cette
optique est utilisée pour faire focaliser un laser au centre d'un piège
magnéto-optique, réservoir d'atomes froids alimentant le piège dipolaire ainsi
créé.
Le dispositif d'observation des atomes piégés est basé sur le même objectif,
qui collecte, avec une grande efficacité, la fluorescence des atomes piégés et
en fait l'image sur une caméra CCD ou une photodiode à avalanche. La résolution
spatiale du dispositif utilisant la caméra permet d'obtenir une image des
atomes capturés, alors que l'on utilise la rapidité de la photodiode à
avalanche pour les études de la dynamique du piège avec une bonne résolution
temporelle.
Après une description détaillée de ce dispositif expérimental, nous montrons
qu'il est possible de réaliser des micro-pièges dipolaires optiques, de
quelques microns cube et contenant une dizaine d'atomes. L'étude de la
dynamique de chargement et de la durée de vie de ces pièges révèle également la
présence de processus de collisions à deux corps. Nous montrons ensuite qu'en
diminuant le taux de chargement il est possible d'observer, en temps réel, un
atome unique piégé pendant quelques secondes. Dans ce régime, un processus de
"blocage collisionnel" limite ce nombre d'atome à un. Pour finir, nous
décrirons la mise en place d'un double piège dipolaire, dans lequel on peut
piéger un atome unique dans chaque site. Ce dispositif ouvre la voie vers
l'étude de l'interaction entre atomes piégés individuellement.

Der volle Inhalt der QuelleThe remarkable capabilities of laser cooling and trapping techniques for neutral atoms have led to great advances in the field of neutral atom-based frequency standards. Among the several atomic systems affording excellent prospects of high stability and accuracy in the optical region, the silver atom is regarded as one of the most promising candidates for an optical frequency standard. This thesis deals with the development of a clock based on neutral silver atoms. The Ag 4d105s2 S1/2 > 4d95s2 2D5/2 transition provides an attractive reference frequency for the following reasons : the 2D5/2 metastable level, which decays by emission of electric quadrupole radiation at 330. 5 nm, has an estimated lifetime of 0. 2 s, corresponding to an ultralow natural linewidth of only 0. 8 Hz. It’s therefore possible therefore to benefit from the long interaction time in an atomic fountain setup. Furthermore, the long-lived state is accessible with a two-photon transition at 661. 2 nm, providing a first-order Doppler-free interaction with atoms of all velocities. As an important technical aspect, the frequency needed to drive the clock transition and to cool the silver atoms (D2 line at 328 nm) can be provided by the same crystal Nd:YLF enable to generate both 1322 nm and 1312 nm. This work details especially the realization of the laser sources for both cooling silver atoms and driving the clock transition by diode-pumped Nd-YLF crystal and intracavity frequency doubling operation in two steps (second and fourth harmonic generation). In addition, the Lignt Induced Atomic Desorption (LIAD) phenomenon is described and observed as an interesting compromise in the case of an optical atomic clock conception

Der volle Inhalt der QuelleThis thesis reports a study of the collisional behavior of atomic Rydberg states with atomic and molecular targets. These collisions are described within the frame of the Impulse Approximation (IA). Methods for the evaluation of the atomic form factor, the key step in the derivation of the cross-section, are proposed and discussed allowing numerous comparisons with experimental data. The quenching cross-sections of high rubidium Rydberg states by molecular perturbers (N₂, CO, NH₃, ND₃) are measured and compared to IA predictions. The influence of the molecular multipole moment as well as of ether relevant physical parameters (energy balance of the reaction) are clearly stated. In the case of dipole molecules the total depopulation is mainly governed by near-resonant energy transfer where the internal energy (atomic or rotational) lest by one colliding partner is gained by the ether. Finally, our theoretical approach is tentatively extended to low-lying excited states and compared to experimental results

Der volle Inhalt der QuelleThe largest satellite of Saturn, Titan, has a nitrogen-rich atmosphere directly bombarded by magnetospheric energetic ions, due to its lack of a significant intrinsic magnetic field. Charge-exchange collisions between the cold neutrals of its exosphere (the upper part of the atmosphere) and the energetic ions from Saturn's magnetosphere produce then energetic neutral atoms (ENAs). The Ion and Neutral Camera (INCA), one of the three sensors that comprise the Magnetosphere Imaging Instrument (MIMI) on the Cassini spacecraft orbiting around Saturn, images these neutrals like photons, measures their fluxes and provides a powerful diagnostic of the interaction between Titan and the kronian magnetosphere. Our work during this PhD thesis was first to model the Titan exosphere, with both thermal and non thermal profiles. An ENA flux calculation model was then developed, compared to observations and completed with a study of the ENA absorption mechanisms. We have also performed a statistical analysis of the MIMI data during the Titan flybys and orbit crossings. Finally, an application on the icy satellite Rhea allowed to infer upper limits for its eventual exosphere

It has been demonstrated that such a fluctuations affect significantly the transport of neutral particles, and in particular the slow particles as molecules and sputtered impurities. That is their penetration depth in the plasma is enhanced in the average. Then turbulent fluctuations are now implemented in the monte carlo transport code EIRENE used for the design of ITER

Der volle Inhalt der QuelleThis work describes the deceleration a sodium atoms beam by means of the Zeeman tuning technique. The deceleration process is studied in details and its demonstration is made using a single laser. We have studied and present the adiabatic following of the atoms along the magnetic field and its relevance to produce slow, high density, flux of neutral atoms. The atoms\' stopping position was varied, by changing the magnetic field profile, in a way to produce slows atoms outside the solenoid. The peculiar shape of the atomic spatial distribution of atoms at rest is explained, the focusing of atoms though a hexapole magnetic field is studied and the trapping of atoms in a magnetic trap is demonstrated
