Single frequency fiber lasers Preface Introduction Fundamental principle and enabling technologies of single frequency fiber lasers Single frequency active fiber lasers Fiber nonlinear single frequency lasers Single frequency pulsed fiber lasers Single frequency fiber amplifiers Representative applications of single frequency fiber lasers Outlook This book gives a contemporary overview of the technologies of single frequency fiber lasers. The development of single frequency fiber lasers is one of the most significant achievements in the field of laser photonics over the past two decades. Owing to the crucial demands of a laser sources with highly stable single frequency operation narrow linewidth low noise scalable to high output power compact and robustness structure fiber lasers have been intensively studied since its introduction to the single frequency laser community and they still continuously proceed to trigger the emergence of new technologies and applications. This book systematically demonstrates the single frequency fiber laser technologies from fundamental principles to state of the art progress. Details of selected typical applications of single frequency fiber lasers are also given and discussed. The reader will acquire a good knowledge of the current situation within this important field
