摘要
泵浦耦合技术是获得高功率光纤激光器的关键技术之一。双包层光纤侧面泵浦耦合技术通过双包层光纤侧面将泵浦光耦合入内包层 ,相对于光纤端面泵浦耦合技术有很多优点。针对于双包层光纤激光器的特点 ,已经发展了多种光纤侧面泵浦耦合技术。概述了目前已经在实验中采用的光纤侧面泵浦耦合技术 。
Pumping coupler technology is one of the critical technologies for high-power fiber lasers.The side-pumping coupler 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.There are several kinds of side-pumping structures according to the characteristics of double-clad fiber laser. In the paper,the side-pumping structures,especially which have been adopt in experiments,are introduced.Moreover the characteristics of these technologies are compared.
