摘要
提出并实现了一种基于对称光纤模式选择耦合器和单模-少模-单模光纤滤波器的环形腔高阶横模光纤激光器,获得了多波长、高纯度的LP11模式激光输出.实验结果表明,该激光器可以稳定地工作在单波长、双波长、三波长和四波长状态,对应的LP11模式激光纯度分别为97.60%、97.54%、97.34%和97.19%.对称光纤模式选择耦合器制造工艺简单,性能稳定,为高阶横模光纤激光的获得提供了一种新的可选方案,在光通信、光传感等领域具有潜在的应用价值.
Abstract
A multi-wavelength ring cavity high-order mode fiber laser based on a symmetrical fiber mode selective coupler(MSC)and single mode-few mode-single mode fiber filter was demonstrated and verified in this paper.The experimental result reveals that the proposed laser can operate stably in single-,dual-,triple-and quadruple-wave-length states with LP11 mode output,whose purities are 97.60%,97.54%,97.34%and 97.19%,respectively.The symmetrical fiber MSC is easy to be fabricated and stable,providing a new choice for the high-order mode fiber laser,which has potential applications in optical communications,optical sensing,etc.
