Book Description
This book is a self-contained collection of scholarly papers targeting an audience of practicing researchers, academics, PhD students, and other scientists. This book describes the rapidly developing field of fiber laser technology filling the very important role of providing students, researchers, and technology managers with valuable, timely, and unbiased information on the subject. The objective of this book is to highlight recent progress and trends in fiber laser technology covering a wide range of topics, such as self-pulsing phenomena in high-power continuous wave (CW) Yb-doped fiber lasers, Q-switched fiber laser, mode-locked fiber laser using carbon nanotubes (CNT), properties of double-scale pulses in mode-locked fiber laser, Brillouin fiber laser, dual-wave length fiber laser (DWFL) for microwave (MHz) and terahertz (THz) radiation generation, tunable fiber laser based on twin core optical fiber, reflective semiconductor optical amplifier (RSOA)-based fiber laser, dissipative soliton phenomena in fiber lasers, noiselike pulses (NLPs) in Yb-doped fiber laser, ultra fast fiber laser, numerical simulation in Q-switched and mode-locked fiber laser, gain saturation in optical fiber laser amplifiers, heat generation and removal in fiber lasers, and different fiber laser based technologies for material processing. We hope that this book will be useful for students, researchers, and professionals, who work with fiber lasers. This book will also serve as an interesting and valuable reference that will impact, stimulate, and promote further advances in the area of fiber lasers

Design and Development of a Novel Multiwavelength Brillouin-erbium Fiber Laser

Languages : en
Pages : 202
Book Description
Multi-wavelength laser sources with constant wavelength spacing are of great interest in dense wavelength division multiplexing (DWDM) communication and sensors system. As the transmission capacity of optical communication systems is approaching a few Tb/s WDM method in recent years, multiwavelength generation technology becomes more important, considering that the complexity and the cost of the source will increase as the number od WDM channel increases. In this thesis, the design and development of a novel architecture of multi-wavelength Brilloui/Erbium fiber laser (BEFL) utilizing a linear cavity fiber loop technique is presented. Simultaneous and stable multiple wavelength lasing in a linear cavity have been achieved. The results are based completely on the experimental work. The requirement of internal feedback that is commonly used for multiple wavelengths Brillouin/Erbium fiber laser using a ring configuration is achieved by the proposed linear cavity design. This design used only a single 980 nm pump laser for its multiple wavelengths operation. Based on the design parameters namely: 980 nm pump power, Brillouin pump wavelength and single mode fiber (SMF) the performance of a novel BEFL is presented in terms of threshold power, Stokes signal peak power, number of Stokes generated , stability of the Stokes and tuningr range. Throughout this work, three lengths of SMF-fiber are used, 1.9 km, 8.8 km and 25 km. The optimization of Brillouin pump wavelength, power and Erbium gain led to a maximum possible number of Stokes. Twenty-two stable output laser lines with 10.88 GHz (0.088 nm) line spacing were obtained at 1558 nm that was the peak of Erbium-doped fiber (EDF). The injected Brillouin pump power into the 8.8 km SMF-fiber was set at 0.9 dBm and the EDF was pumped by 100 mW of 980 nm pump laser. The most efficient cascaded Brillouin Stokes operation occured at the peak of Erbium gain centered on 1558 nm. The number of Stokes decreased as the Brillouin pump increased in the highest region of Erbium gain. On the contratry, the number of Stokes was proportional to the intensity of the Brillouin pump power outside this wavelenght range. The best performance and conversion efficiency of Brillouin pump to the BEFL signal occur at the lower levels of injected Brillouin pump power. A low threshold of 4 mW pump power with 2.3 mW launched Brillouin pump into the 8.8 km of SMF-fiber at 1558 nm was obtained. The tuning range of the Stokes signal must be taken into account both the Brillouin and EDF pump power, at a fixed EDF pump power the Stokes signal can be tuned wider at a higher Brillouin pump power while higher EDF pump power produces smaller tuning range.
