摘要
双包层光纤侧面耦合技术将泵浦光从光纤侧面耦合进入内包层,与端面耦合技术相比,更有利于高功率光纤激光器的实现。介绍了角度磨抛、微棱镜、V形槽、内嵌反射镜、衍射光栅多种侧面泵浦耦合技术的结构、原理以及系统性能参数,并分析了各种技术方案中需要解决的问题。
The side-coupling technology for double-clad fiber can transfer pumping light into inner cladding through the side of the fiber. It has many advantages over end-pumping technology on high power fiber lasers. There are several kinds of side-coupling technology, such as fiber angle-polished, micro-prism, V-groove, embedded mirror and diffraction grating side-coupling. The structures, theories and performance parameters of these technologies are introduced and the problems of each method are analyze.
