Pdf on tunable laser




















From a renaissance in laser spectroscopy to Bose-Einstein condensation, the one nexus is the tunable laser. Tunable Laser Applications describes the physics and architectures of widely applied tunable laser sources. Fully updated and ex. Author : Linn F. Mollenauer,Jonathan C. White,Clifford R. Following an introductory chapter on common general principles, the remaining chapters - all written by leading experts in the field - each treat a particular class of tunable laser or process.

In each case, a theoretical treatment is combined with a detailed practical description of the lasers and their operation. The book is written so as to be readily accessible to researchers and students alike. It is especially intended to enable the non-expert to choose the most appropriate tunable laser for a specific application.

In this second edition an added chapter with extensive references to recent literature reviews the advances that haveoccured since the publication of the original edition. Author : N. Atomic and molecular spectroscopy, interferometry, lightening triggering, imaging, laser radar, lidar and gyroscopes are discussed. The work focuses on various sources of coherent radiation such as optical parametric oscillators, external cavity semiconductors lasers, and dye, gas, C02, ultrashort-pulse and free-electron lasers.

Author : Mool C. In this new, updated second edition editor Mool Gupta is joined by John Ballato, strengthening the handbook with their combined knowledge and the continued contributions of world-class researchers.

New in the Second Edition: Information on optical fiber technology and the economic impact of photonics Coverage of emerging technologies in nanotechnology Sections on optical amplifiers, and polymeric optical materials The book covers photonics materials, devices, and systems, respectively.

An introductory chapter, new to this edition, provides an overview of photonics technology, innovation, and economic development. Resting firmly on the foundation set by the first edition, this new edition continues to serve as a source for introductory material and a collection of published data for research and training in this field, making it the reference of first resort.

Especially 4 new chapters on Fiber Optics, Integrated Optics, Frequency Combs and Interferometry reflect the changes since the first edition. Features Contains over two-color illustrations.

Includes over comprehensive tables with properties of optical materials and light sources. Emphasizes physical concepts over extensive mathematical derivations. Chapters with summaries, detailed index Delivers a wealth of up-to-date references.
