"Given the combination of broad scope and technical depth, both researchers and users of fiber lasers alike will find this book to be a valuable addition to their technical library." — Jeffrey W. Nicholson, OFS, Norcross, Georgia, USA"… gives a comprehensive overview on the current status of fiber laser technology, covering the underlying physics and various technological issues as well as applications. It is useful to have a combination of two authors with quite different backgrounds, such that all these aspects can be treated. Compared with some older books on fiber lasers and amplifiers, there is more useful material on various practical aspects, e.g. in the areas of fiber characterization, components for fiber lasers and applications. The book should thus be useful both for researchers in the field and for people working on fiber laser technology in the commercial area." — Rüdiger Paschotta, RP Photonics Consulting GmbH, Bad Dürrheim, Germany"The book is a comprehensive look at optical fibers, Fiber lasers and their applications written by leading experts in the field. The explanations are clear and intuitive and work is well referenced."—Jay W. Dawson, Lawrence Livermore National Laboratory, Livermore, California, USA"This book is a useful guide for graduate students and engineers who are entering the complex and rapidly developing field of fiber lasers, and is a valuable reference for scientists who are new to fiber lasers or for veterans in the field." —Optics & Photonics News, May 2017
