Book Description
Cette étude concerne les problèmes d’analyse de la composition chimiques des nuages de particules atmosphériques par voie passive optique. Un modèle à l'ordre 1 de diffusion validé par un code de calcul utilisant une méthode de MONTE-CARLO a permis la réalisation d'un bilan radiatif spectral. Ce modèle a servi ensuite à l’élaboration d’un processus expérimental permettant la détection et l'analyse à distance des nuages composés de particules sphériques. Le processus expérimental s’applique au cas des nuages transparents et au cas des nuages opaques ou non soumis au rayonnement des fonds. Deux types de mesures ont alors été établis, l'une par transmission et l'autre par émission propre des particules du nuage. Dans chacun des cas l’influence de la concentration massique est supprimée par deux mesures simultanées à deux longueurs d’onde. Le choix de la première longueur d’onde correspond à la fréquence de vibration du groupement fonctionnel de la molécule à détecter. La deuxième longueur d'onde est choisie pour donner une dynamique maximale aux paramètres de mesure. Les résultats expérimentaux confirment les modèles théoriques en transmission et en émission propre. La validation a été effectuée pour un nuage d'eau et pour un nuage d'une huile (SF99) possédant une bande d'absorption entre 9 et 10 microns.

Quantum Mechanics, Volume 3
Author: Claude Cohen-TannoudjiPublisher: John Wiley & Sons
ISBN: 3527345558
Category : Science
Languages : en
Pages : 790
Book Description
This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.
Organic Solid-State Lasers
Author: Sébastien ForgetPublisher: Springer
ISBN: 3642367054
Category : Science

Pages : 179
Book Description
Organic lasers are broadly tunable coherent sources, potentially compact, convenient and manufactured at low-costs. Appeared in the mid 60’s as solid-state alternatives for liquid dye lasers, they recently gained a new dimension after the demonstration of organic semiconductor lasers in the 90's. More recently, new perspectives appeared at the nanoscale, with organic polariton and surface plasmon lasers. After a brief reminder to laser physics, a first chapter exposes what makes organic solid-state organic lasers specific. The laser architectures used in organic lasers are then reviewed, with a state-of-the-art review of the performances of devices with regard to output power, threshold, lifetime, beam quality etc. A survey of the recent trends in the field is given, highlighting the latest developments with a special focus on the challenges remaining for achieving direct electrical pumping of organic semiconductor lasers. A last chapter covers the applications of organic solid-state lasers.
