摘要
自光纤激光器问世以来,随着半导体材料与光纤制备技术的快速发展,光纤激光器的输出功率由毫瓦级提高到了万瓦级。然而,随着输出功率的增加,光纤激光器在低输出功率下未表现出的诸多现象逐渐显现,如光纤热损伤、非线性效应、模式不稳定等,这些现象限制了光纤激光器的应用,因此对掺镱光纤的质量要求越来越高。针对高功率掺镱光纤的制备工艺、掺杂组分及结构设计等方面进行了讨论,分析了高功率掺镱光纤的热稳定性、功率稳定性及模式稳定性的研究现状,并总结了其发展趋势。
Abstract
Since the emergence of fiber lasers, the output power of fiber laser has been increased from milliwatt level to myriawatt level along with the rapid development of semiconductor material and fiber fabrication technology. However, with the increasing of output power of fiber laser, many phenomenons which are not shown at a low output power have appeared gradually, such as fiber thermal damage, nonlinearity effect and mode instability, which limit the application of fiber laser. Therefore, the demand for the quality of Yb-doped fiber is higher and higher. The fabrication technologies, doping components and structural design of high power Yb-doped fibers are discussed. The status and development tendency of thermal stability, power stability and mode stability of high power Yb-doped fiber are analyzed.
