摘要
高功率铒镱共掺光纤激光器因具有“人眼安全”和在光纤及大气中的低损耗特性,广泛用于光纤通信、激光雷达、卫星遥感和精密测量中。简要介绍了铒镱共掺光纤及其激光系统的发展历程,着重阐述了其在高功率窄线宽方面的最新研究进展,分析了制约铒镱共掺光纤激光器功率攀升的因素。针对镱波段放大的自发辐射和光纤热效应,分别从光纤材料与结构和激光系统结构两个方面进行优化,以实现更高输出功率的铒镱共掺光纤激光器。
Abstract
High-power erbium-ytterbium codoped fiber lasers have been widely applied to optical fiber communication, lidar, satellite remote sensing, and precision measurement owing to its “eye safety” and low loss characteristics in both optical fibers and atmosphere. This study briefly introduces the developments of the erbium-ytterbium codoped fiber and associated laser system and emphatically expounds the latest progress in research on erbium-ytterbium codoped fiber lasers with high power and narrow linewidth. Additionally, we analyzes factors which restrict the increase of power of the erbium-ytterbium codoped fiber laser. In view of ytterbium-band amplified spontaneous emissions and optical fiber thermal effects, optical fiber and laser system structures are optimized to realize an erbium-ytterbium codoped fiber laser with higher output power.
