Available in PDF, EPUB and Kindle. Book excerpt: Un des plus grands enjeux de l’optoélectronique organique est la réalisation de la première diode laser organique (en pompage électrique), qui présente un très fort potentiel pour de nombreuses applications. À l’instar de ce qui s’est produit dans le domaine de l’optoélectronique inorganique en transformant une LED en une LD, la course est engagée pour convertir une OLED en une OLD. Cela passe par le développement de solutions innovantes afin de surmonter les difficultés inhérentes aux matériaux organiques et au pompé électrique. Une introduction aux lasers organiques présente les éléments de physique, les matériaux et les technologies qui permettent de comprendre les bases de ces lasers et de saisir les progrès accomplis. Il offre également des pistes pour envisager les évolutions futures vers la diode laser organique.

Download or read book Organic Lasers written by Marco Anni and published by CRC Press. This book was released on 2018-05-24 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past 30 years, organic conjugated molecules have received a lot of attention in research because of their unique combination of active properties typical of semiconductors and the technological appeal typical of plastic materials. Among the different applications proposed for organic materials, organic lasers are quickly approaching the performance required in real devices, while research on novel active materials is still ongoing. The book covers the basic aspects of the measurement techniques of optical gain and amplified spontaneous emission (ASE) in organic films as well as the photophysics of organic materials that can be understood using ASE measurements. It reviews the recent advances in the development of new active materials for organic lasers as well as the actual state of the art of scattering-assisted random lasers and of strongly coupled organic microcavities, both promising interesting developments in the near future. Finally, it gives a detailed review of the state of the art of the organic lasers actually closest to real applications, namely external cavity lasers and distributed feedback lasers. The book is unique that it covers basic aspects, technological aspects, and systems, which are still a subject of basic science research.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a review of past and current studies and future plans of the Laser Laboratory in Cincinnati and some of the contributions of laser research groups in other medical centers. Special thanks are due to the Directing Physicist of the Laser Labora tory, R. James Rockwell. Without his advice, constant supervision and corrections, this enthusiastic investigator would continue to upset even many more people than he has done already. The excuse, of course, is to stimulate much needed interest and controlled research and development of the laser for biology and medicine. The Associate Research Physicist, Ralph Schooley, has worked with many phases of laser research but especially in Q spoiling, Raman spectroscopy, and the almost alchemy of holography. Holography, as of now, provides many opportunities for Gumperson's Law, "If anything can go wrong, it will. " Sincere appreciation is expressed to the Surgeons in the Laser Labora tory, who have supplied clinical and investigative surgical supervision often under great difficulties, Dr. V. E. Siler and Dr. Bruce Henderson. We are grateful for help from the Directing Biologist of the Laser Labo ratory, Edmond Ritter, the Director of Laser Neurosurgery, Dr. Thomas Brown and the Professor of Neurosurgery, Dr. Robert McLaurin, for important and basic work in laser neurosurgery. Special thanks are given to Robert Meyer, who has given most of the treatments in careful and skillful fashion, and his associate, Robert Otten.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de cette thèse est l'étude de nouveaux matériaux et d'architectures innovantes pour les lasers organiques à l'état solide. Le premier axe de ce travail est consacré à la caractérisation laser d'une nouvelle petite molécule organique appelée "fvin". L'émission stimulée dans le rouge (vers 650 nm) a été observée dans une couche pure de ce matériau, ce qui est en général impossible dans les colorants organiques en raison du phénomène de "concentration quenching". La méthode de ruban de pompage de longueur variable (Variable Stripe Length (VSL) technique) a été utilisée pour étudier et mesurer le gain de ce matériau. L'effet laser a été démontré dans une cavité à réseaux de Bragg distribués (DBR) ainsi que sous la forme de laser aléatoire à des intensités de pompe élevées. Le deuxième axe de cette thèse est dédié au design, à la réalisation, à la caractérisation et à la modélisation d'une nouvelle architecture laser organique à cavité externe appelée VECSOL (inspirée de l'architecture traditionnelle des VECSELs inorganiques). Le milieu à gain est une couche de PMMA dopée avec un colorant (Rhodamine 640), déposée par "spin-coating" sur un miroir plan diélectrique. Le laser a été caractérisé avec deux sources de pompage de durées d'impulsion différentes (0.5 ns et 7 ns). Nous avons démontré une émission accordable (sur plus de 40 nm), un faisceau limité par la diffraction et un record d'efficacité de 57% dans une configuration optimisée. La dynamique de l'émission laser a été modélisée grâce aux équations de taux de Tang-Statz-de Mars, adaptées à la géométrie VECSOL. La cavité ouverte de l'architecture réalisée a permis, en outre, l'obtention d'une émission ultraviolette accordable grâce au doublement de fréquences intracavité dans une géométrie VECSOL modifiée.
