中文摘要： 单频光纤激光器具有重要科学及战略价值，被广泛应用于高分辨干涉仪、光纤传感和激光雷达等重大领域中，近年来单频光纤激光器的研究主要是围绕结构设计、调谐技术、线宽压窄等方面展开，取得了一定成果，但总体停留在单项指标的提高上，整体性能不高，特别是同发达国家相比，我国在单频光纤激光器科学研究和生产技术方面非常薄弱，导致国内相关领域应用的单频光纤激光器一直依赖进口。本项目针对现有单频光纤激光器的不足提出了新型（新波段和新结构）高性能单频光纤激光器的研制方法，结合对特殊光纤的研制、超窄线宽超低噪声单频连续光纤激光器科学问题的探索,获得整体指标先进的单频光纤激光器设计方案和制造方法，同时深入研究高功率连续和高能量脉冲单频光纤激光器的科学局限，取得国际领先的高功率和高能量单频光纤激光输出。该项目的成功完成必将推动我国单频光纤激光器的研究水平，进而推动相关领域应用和相关器件的研制水平，服务于我国现代化建设中来

英文摘要： Single frequency fiber laser is an advanced laser with high performance, which has very important scientific and strategic value. It has been widely used in high-resolution interferometer, coherent communications, fiber optic sensing, LADAR and other fields. Currently, the research of single frequency fiber laser mainly focuses on the laser cavity design, tuning techniques, narrow linewidth and related devices. Some good results have been achieved. But most of achievements are only for the individual parameters, and the overall performance is not satisfied for applications. Especially, in our country, the research level of single frequency is relatively poor comparing to developed countries. And our commercialization in China for single frequency fiber lasers is nearly zero, leading to limitations and restrictions in some important high-tech fields by foreign countries. In this proposal, specialty fibers and high-performance single-frequency fiber lasers (new band and a new structure) are proposed and will be developed. We will deeply explore the scientific problems for ultra-narrow linewidth and ultra-low noise single-frequency continuous fiber lasers. We will design and fabricate single-frequency fiber lasers with advanced overall parameters（including high power or high pulse energy）. And the high power CW and high energy pulsed single-frequency fiber lasers will be developed. The developments of all the proposed single frequency fiber lasers with new wavelengths and new configurations will surely promote our research level for single-frequency fiber lasers, which will strongly push the development level of the related applications and devices, and serve our modern society and national defense construction.
