Book Description
LA PREMIERE PARTIE DU MEMOIRE PRESENTE UNE METHODE DE CONCEPTION DE DIODES LASER GAALAS/GAAS A RUBAN VSIS EMETTANT DANS LE SPECTRE VISIBLE. UN MODELE ANALYTIQUE COMPLET ET ORIGINAL TIENT COMPTE DES PROPRIETES DE LA COUCHE ACTIVE AINSI QUE DES MECANISMES DE DECONFINEMENT ELECTRIQUE ET OPTIQUE DANS LES SENS TRANSVERSE ET LATERAL AUX HETEROJONCTIONS. SUR CETTE BASE, LES PERFORMANCES LIMITES DE CE COMPOSANT SONT ANALYSEES AFIN DE DEDUIRE LES PLUS COURTES LONGUEURS D'ONDE D'EMISSION COMPATIBLES AVEC UN FONCTIONNEMENT EN REGIME CONTINU A TEMPERATURE AMBIANTE. LA DEUXIEME PARTIE DU MEMOIRE CONCERNE LE PROCESSUS TECHNIQUE DE REALISATION DE CES DIODES LASER

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.

Book Description
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.
