This book was released on 2002 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: La première partie de ce travail présente quelques éléments théoriques de l'optique non linéaire en rapport avec les oscillateurs paramétriques optiques en régime nanoseconde. Après un court rappel historique sur l'optique non linéaire, nous donnons les équations de propagation de trois ondes couplées en milieu non linéaire, nous exposons le principe de l'accord de phase par biréfringence et celui du quasi-accord de phase, puis nous donnons des solutions analytiques aux équations de propagation dans le cas des ondes planes. Nous présentons ensuite les différents processus paramétriques du deuxième ordre permettant d'exploiter les propriétés des cristaux non linéaires. La deuxième partie présente le contexte de l'étude menée dans le cadre d'une collaboration entre le Laboratoire Charles Fabry de l'Institut d'Optique et la société CILAS. Après un état de l'art sur les expériences publiées concernant la génération d'ondes entre 2 mM et 5 mM, nous présentons les deux configurations que nous étudions par la suite. Dans la troisième partie nous développons les expériences menées sur la première configuration n'utilisant que des cristaux en accord de phase par biréfringence fonctionnant à proximité de la dégénérescence. Son principe réside en la mise en série d'un OPO à base de KTP et d'un OPO à base de ZGP. Pour le premier OPC nous démontrons l'efficacité de l'utilisation de plusieurs cristaux de KTP montés en compensation de double réfraction. Le rendement énergétique de 1 mM vers l'onde complémentaire atteint 29 %. Nous utilisons cet OPO en tant que source de pompage pour un OPO à base de ZGP, ce qui nous permet d'atteindre un rendement énergétique de 1 mM vers la bande 3-5 mM de 12 %. La quatrième partie concerne les expériences menées sur la seconde configuration, constituée de deux OPO mis en parallèle à base de cristaux en quasi-accord de phase. Nous évaluons successivement les performances d'OPO à base de PPKTP, PPLN puis PPRTA, à basse et à haute cadence.
Download or read book Quantum Mechanics Volume 3 written by Claude Cohen-Tannoudji and published by John Wiley & Sons. This book was released on 2019-12-16 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.

Download or read book Inertial Navigation Systems Analysis written by Kenneth Robert Britting and published by GNSS Technology and Applicatio. This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Out-of-print for years, this highly sought-after volume, remains the most popular reference on inertial navigation systems analysis. Finally, this classic book is back in print and readily available only from Artech House. Authored by a pioneer in the field, this authoritative resource focuses on terrestrial navigation, but is also useful for air and sea applications. Packed with valuable, time-saving equations and models, the book helps engineers design optimal navigation systems by comparing the performance of the various types of system mechanizations. Although applications and technology have changed over the years, this book remains the best source for fundamental inertial navigation system knowledge, from notational conventions, reference frames, and geometry of the earth, to unified error analysis, self-alignment techniques, and the development of a system error model. This well-illustrated, timeless reference belongs on the shelf of every practicing engineer working in this area.

This book was released on 2001-11-30 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in computer applications has led to a new attitude to applied logic in which researchers tailor a logic in the same way they define a computer language. In response to this attitude, this text for undergraduate and graduate students discusses major algorithmic methodologies, and tableaux and resolution methods. The authors focus on first-order logic, the use of proof theory, and the computer application of automated searches for proofs of mathematical propositions.

What Are the Controversies Surrounding Global Warming? What Are the Solutions for Global Warming?
Download or read book Fundamentals of Human Computer Interaction written by Andrew F. Monk and published by Academic Press. This book was released on 2014-06-28 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Human-Computer Interaction aims to sensitize the systems designer to the problems faced by the user of an interactive system. The book grew out of a course entitled ""The User Interface: Human Factors for Computer-based Systems"" which has been run annually at the University of York since 1981. This course has been attended primarily by systems managers from the computer industry. The book is organized into three parts. Part One focuses on the user as processor of information with studies on visual perception; extracting information from printed and electronically presented text; and human memory. Part Two on the use of behavioral data includes studies on how and when to collect behavioral data; and statistical evaluation of behavioral data. Part Three deals with user interfaces. The chapters in this section cover topics such as work station design, user interface design, and speech communication. It is hoped that this book will be read by systems engineers and managers concerned with the design of interactive systems as well as graduate and undergraduate computer science students. The book is also suitable as a tutorial text for certain courses for students of Psychology and Ergonomics.
