ABSTRACT High power operation of narrow linewidth optical fiber amplifiers is usually limited by the onset of stimulated Brillouin scattering. In this paper, we present results demonstrating over 500 Watts of power in a single mode beam from a fiber designed to suppress stimulated Brillouin scattering through a reduction in the overlap of the optical and acoustic fields. Simulations demonstrate the potential for this fiber to achieve greater than 1000 Watts of output power. (C) 2007 Optical Society of America.

    ABSTRACT: From a materials perspective optical fibers are victims of their own success. The advent of the laser, 50 yr ago, coupled with an insatiable demand for information enabled by light‐based communications, ushered in a golden age of glass science and engineering. It is somewhat ironic that the staggering ubiquity of information today, which is carried globally and almost instantaneously via optical fibers, is enabled largely by one material—silica—into which only a few components are added. The richness of the Periodic Table has largely been forgotten. The purpose of this study was to rethink the materials that can be used to make commercially relevant optical fibers and describe the extraordinary properties, with stimulated Brillouin scattering being the primary exemplar, of fibers made from otherwise ordinary materials. In particular, this study focuses on the use of the molten core approach to optical fiber fabrication and the novel yet practical fibers that can be produced. This study is purposely provocative and aims to reassert the centrality (and simplicity and beauty) of glass science as the best approach to meet future challenges for high‐performance optical fibers.

    ABSTRACT: Alumina is an indispensable dopant in modern optical fiber technology, particularly due to its important role played in the recent developments of optical fiber amplifiers and high-power fiber lasers over the last decade or so, which have revolutionized the telecommunication systems, and the industrial laser landscapes, respectively. In this paper, Alumina-doped optical fibers advanced through the outside vapor deposition process and their key attributes in the respective applications are reviewed, with Alumina both as a sole dopant for its potential use in the low-loss transmission lines and as a co-dopant for active use in the high-brightness, high-power fiber laser applications.

    ABSTRACT: A complete theoretical model on the stimulated Brillouin scattering (SBS) for multi-mode fibers (MMF) is developed by solving the optical-acoustic coupling wave equations. It shows that all optical modes of the signal and of SBS are coupling each other through proper acoustic waves. The Brillouin gain spectrum of each optical mode pair is obtained by certain three-wave couplings (optical-acoustic-optical). The model is further coupled with an optical amplification model on the fiber lasers to take the mode competition into account. By applying the model to a large mode-area double cladding fiber, it is found that the multi-acoustic mode combination plays an important role in the SBS coupling between optical higher order modes (HOM). While for double-mode (fundamental mode +HOM) performance, the SBS threshold increases gradually along with the increase of HOM content. It is also found that the SBS process in the fiber amplifiers can be completely different comparing with that of the passive fiber, because the mode competition not only changes the mode contents of the signal power but also influences the initial growth rate of SBS noise. The Al/Ge co-doped MMF is investigated theoretically as well, and is shown to be able to suppress SBS significantly. Finally we compare our model with a SBS experiment for a MMF, main theoretical predictions agree with the experiment well.
