Book Synopsis Application des diodes laser infrarouges accordables à deux problématiques by : Sébastien Dusanter
Download or read book Application des diodes laser infrarouges accordables à deux problématiques written by Sébastien Dusanter and published by . This book was released on 2002 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: La spectroscopie d'absorption infrarouge par diode laser accordable permet d'allier sensibilité, sélectivité et résolution temporelle élevées. Nous avons appliqué cette technique à la mesure de polluants atmosphériques en traces et à la cinétique de réactions élémentaires en phase gazeuse. En métrologie, nous avons développé un protocole original et performant : mesure par augmentation de pression. Il a été appliqué à la mesure en protoxyde d'azote, en formaldéhyde, en acétaldéhyde et en 1,3-butadiène, dans l'air ou les gaz d'échappement automobile. Ce travail représente un premier pas vers l'élaboration d'un instrument de terrain compact et transportable. Le dispositif de cinétique, où les réactions sont initiés par photolyse laser, a été validé par l'étude des réactions des radicaux formyle et hydroxyméthyle avec l'oxygène. Une étude préliminaire de la constante de décomposition unimoléculaire du radical pivaloyle a été effectuée.
Book Synopsis Organic Solid-State Lasers by : Sébastien Forget
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.
Book Synopsis Laser: 50 Years Of Discoveries by : Fabien Bretenaker
Download or read book Laser: 50 Years Of Discoveries written by Fabien Bretenaker and published by World Scientific. This book was released on 2014-10-27 with total page 185 pages. 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.
