Abstract

The invention discloses an encapsulating structure and an encapsulating method of a combiner. The encapsulating method comprises the following steps of: 1, encapsulating a manufactured combiner product on a substrate and fixing optical fibers at the two ends of the substrate by using primary glue; 2, putting the substrate on which the combiner is arranged into a circular pipe and sealing the two ends of the circular pipe by using secondary glue; and 3, encapsulating the circular pipe into a metal box by using third glue, making an input optical fiber and an output optical fiber of the combiner extend out of the two ends of the metal box and putting gum caps into the two ends of the metal box so as to protect the optical fibers. The encapsulating method has a simple process. The encapsulated combiner has the characteristics of high long-term working stability, high radiating reliability and the like.

Description

technical field [0001] The invention relates to the packaging of an optical fiber bundle combiner, in particular to a packaging structure and a packaging method of a high-power optical fiber bundle combiner. Background technique [0002] With the rapid development and maturity of fiber laser technology, the characteristics and advantages of fiber laser have been gradually recognized by people. Fiber laser has been widely used in national defense, industrial processing, medical and other fields, and the market demand and application are increasing year by year. , which is bound to create a large demand for fiber combiners. [0003] Fiber combiner is one of the core components of high-power fiber lasers. It is currently the most effective pump coupling device. It can efficiently couple the energy of multiple lasers into one optical fiber for transmission. The power used is generally tens of watts, Hundreds of watts or even kilowatts, such a high-power operation, puts forward ...
