Integrated fiber components enable compact and robust laser systems but are usually not available with specialty fibers. However, specialty fibers allow power scaling of fiber lasers and amplifiers with all advantages of these fiber designs. In this context, chirally-coupled-core fibers show promising properties for optical fiber components. In this paper, we present the development of a highly-integrated signal and pump combiner in chirally-core-fibers using a side-pumping technology. Combining up to four fiber-coupled pump diodes, a pump-light limited power handling of 600 W can be achieved with an efficiency of 78%. The combiner was tested in a side-pumped single-frequency all-fiber amplifier but can also be implemented in almost any fiber laser or amplifier.

手性耦合芯光纤中的高度集成信号和泵浦组合器


集成光纤组件可实现紧凑而坚固的激光系统，但通常不适用于特种光纤。然而，特种光纤允许光纤激光器和放大器的功率缩放，并具有这些光纤设计的所有优点。在这种情况下，手性耦合芯光纤对于光纤组件显示出有前景的特性。在本文中，我们介绍了使用侧面泵浦技术的手性芯光纤中高度集成的信号和泵浦组合器的开发。结合多达四个光纤耦合泵浦二极管，可以实现 600 W 的泵浦光有限功率处理，效率为 78%。该组合器在侧泵单频全光纤放大器中进行了测试，但也可以在几乎任何光纤激光器或放大器中实施。
