The fixing of the stripper increases the number of fusion points, which leads to an increase in energy loss. At the same time, the stripper dissipates this part of the pump light in the form of heat, so that this part of the pump light is not used, reducing the conversion efficiency of the laser, resulting in energy loss. waste of

Abstract
The invention discloses an optical fiber with pumping light reflection function and its manufacturing and testing method, comprising an optical fiber body, a first grating and a second grating; The fiber core of the body is used to output laser light of a specific wavelength; the second grating is located in the cladding and fiber core of the fiber body, and is used to reflect the pump light in the cladding and fiber core to the fiber body. By installing a second grating, the pump light in the fiber body is reflected back into the resonator to continue to oscillate by the second grating, thereby forming laser light, which is output through the first grating, thereby reducing energy waste and further improving the output of the fiber laser The output power of the laser. And the method of making the first grating and the second grating in the fiber body is adopted to reduce the number of fusion points, thereby reducing energy loss.
Description
Technical field [0001] The present invention belongs to the field of optical device technology, specifically relates to a optical fiber having a pump light reflection function and a method of making and testing it. Background [0002] Fiber lasers were born in the second year of the invention of the laser and have an almost as long history as lasers. With the decline in the cost and price of fiber lasers, the application scenarios of fiber lasers are becoming more and more extensive, and the market requirements for fiber lasers are getting higher and higher, especially for the conversion efficiency of light lasers. And in the context of energy saving and emission reduction, it is particularly important to improve the conversion efficiency of fiber lasers. [0003] In current fiber lasers, the pumped light produced by the pump laser oscillates through the resonators formed by two endoscopic gratings and gain fibers to form a laser and output the laser. Among them, when the pump li...
