Download or read book tude et caract risation par fluorescence induite par laser d un jet puls d oxyg ne atomique written by Pascale Pezé and published by . This book was released on 1993 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: La première partie de cette thèse est consacrée à la position du problème de la connaissance d'un jet pulsé d'oxygène atomique rapide mis au point afin de simuler l'attaque des matériaux par l'oxygène atomique en orbite basse. Après un rappel des méthodes de caractérisation de l'oxygène atomique, la fluorescence induite par laser est présentée en détails dans la deuxième partie. La prise en compte de tous les mécanismes radiatifs intervenant dans cette technique, ainsi qu'une description détaillée de la géométrie du volume fluorescent, ont permis d'obtenir de bons résultats quantitatifs en ce qui concerne la détection de l'oxygène atomique dans son état fondamental. Des expériences visant à comparer les résultats obtenus par fluorescence induite par laser à ceux obtenus par titration par le dioxyde d'azote valident cette étude. Une troisième partie est consacrée à l'application de la fluorescence induite par laser à la caractérisation spatio-temporelle du jet d'oxygène atomique. Les distributions de temps de vol des atomes d'oxygène à l'état fondamental sont enregistrées pour différentes conditions de création de jet : l'analyse de ces résultats a permis de conclure que la majorité des atomes se situe au centre du jet, leurs distributions sont des Maxwelliennes avec formation d'une couche de Knudsen et l'ajustement des paramètres de création de jet est essentiel et très délicat à réaliser. Enfin une dernière partie est consacrée à l'application de la fluorescence induite par laser à la détection de l'oxygène moléculaire dans son état fondamental. La bande (0,0) de la transition X-B est excitée dans de l'oxygène moléculaire pur. Les résultats de cette étude montrent que la fluorescence induite par laser n'est pas adaptée à la détection de l'oxygène moléculaire dans notre jet (seuil de détection trop élevé).

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.
Download or read book Organic Solid State Lasers written by Sébastien Forget and published by Springer. This book was released on 2013-07-03 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This unique book provides an overview of the principle and applications of lasers enriched with numerous illustrations.Being over fifty years old, lasers continue to amaze us. Their performance characteristics are constantly reaching new limits, and the scope of their applications continues to expand. Yet, it took years of effort by teams of physicists to transform the fundamental notions of Einstein into the first experimental beam of laser light. And history is still going on as fundamental research is now triggered by its remarkable properties.This book addresses every aspects of laser light, from its fundamental principles to its industrial applications, at a level particularly suited for high school teachers, students, and anybody curious about science and technology.
Download or read book Physical Properties of Amorphous Materials written by David Adler and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Institute for Amorphous Studies was founded in 1982 as the international center for the investigation of amorphous mate rials. It has since played an important role in promoting the und er standing of disordered matter in general. An Institute lecture series on "Fundamentals of Amorphous Materials and Devices" was held during 1982-83 with distinguished speakers from universities and industry. These events were free and open to the public ,and were attended by many representatives of the scientific community. The lectures themselves were highly successful inasmuch as they provided not only formal instruction but also an opportunity for vigorous and stimulating debate. That last element could not be captured within the pages of a book I but the lectures concentrated on the latest advances in the field I which is why their essential contents are he re reproduced in collective form. Together they constitute an interdisciplinary status report of the field. The speakers brought many different viewpoints and a variety of back ground experiences io bear on the problems involved I but though language and conventions vary I the essential unity of the concerns is very clear I as indeed are the ultimate benefits of the many-sided approach.
Download or read book Historical Dictionary of Pakistan written by Shahid Javed Burki and published by . This book was released on 1999 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pakistan is unlike most other countries in the emerging world. It is one of the two nations – the other being the state of Israel – founded on the basis of religion. Although it was created to provide a homeland for the Muslim community of British India, in its original form it was able to accommodate only about half of the people of Islamic faith who lived in the subcontinent. Pakistan’s birth in 1947 resulted in one of the largest movements of people in human history when some 14 million people left their homes, with 8 million Muslims leaving India for what is now Pakistan and 6 million Hindus and Sikhs moving in the opposite direction. This was the first large-scale incidence of ethnic cleansing the world was to witness. --
Download or read book International Humanitarian Law and Terrorism written by Andrea Bianchi and published by Hart Publishing. This book was released on 2011-07-01 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book carefully and thoroughly analyses the legal questions raised by the phenomenon of terrorism, and past and recent efforts to fight it, from the perspective of international humanitarian law (IHL). The objective is to substantially contribute to a better understanding of the issues surrounding the content and applicability of IHL as it applies to terrorism as well as to analyse and contextualise the current debates on these controversial and critically important questions. While due heed is paid to doctrinal debates, particular emphasis is placed on the practice of social actors, particularly, although not exclusively, States. The analysis of their actual conduct as well as their expectations about the interpretation and application of the law is crucial to establishing an interpretive consensus on when and how IHL is relevant to regulate acts of terrorism. The approach of the book is analytical and discursive, rather than prescriptive. Thus the reader will find the relevant rules of IHL and other legal regimes as regards terrorism, but also the debates over their application, the contradictions in State practice and the impact these may have upon IHL's evolution and implementation. The aim is to provide legal practitioners, as well as those in military, political and academic circles, with a useful reference point. Hopefully the book will also prove useful to other readers who will find its content and easy-to-read style an encouragement to getting acquainted with a topical subject, traditionally thought to be reserved for legal specialists. This book was cited with approval by the US Court of Appeals in Salim Ahmed Hamdan v United States of America, 16th October 2012
