Problems solved by technology

The power density in the high-power fiber laser core is very high, and the heat generated is also high. During use, the active fiber must be coiled for heat dissipation. If the fiber is not coiled properly, it is easy to generate stress. It is easy to be damaged, resulting in local concentration of energy, which leads to fiber burnout. There are two methods of coiling the active fiber of fiber lasers on the market: one is the method of coiling the fiber on an aluminum cylinder, and the fiber is threaded. Coiled on a smooth cylinder, in order to prevent the optical fiber from slipping off the cylinder, the optical fiber and the optical fiber must not only be in direct and close contact, but als

Abstract

The invention discloses an active optical fiber winding device and an optical fiber winding method for an optical fiber laser. The winding device is a radiating disc with a conical shape; continuously arranged winding slots are formed in the conical surface of the radiating disc; each winding slot is provided with two symmetrical slot walls; the section included angle alpha of every two slot walls is 90 degrees; an interval is remained between the adjacent optical fibers in the winding slots. Stress caused by the direct contact between the optical fibers is avoided, a better radiating effect is achieved and the burning loss phenomenon is avoided.

Description

technical field [0001] The invention relates to a coiling device for an active optical fiber of a fiber laser and a method for coiling the optical fiber. Background technique [0002] At present, as the representative of the third-generation laser technology, fiber lasers have incomparable advantages over solid-state and gas lasers, including small size, good beam quality, high electro-optical conversion efficiency, low operating costs, and high processing accuracy; fiber lasers have been widely used It is used in the high-end manufacturing industry of material processing and mechanical processing, and the market prospect is very broad. The power density in the high-power fiber laser core is very high, and the heat generated is also high. During use, the active fiber must be coiled for heat dissipation. If the fiber is not coiled properly, it is easy to generate stress. It is easy to be damaged, resulting in local concentration of energy, which leads to fiber burnout. There...
