Abstract

The invention discloses a cooling structure, a laser amplifier and an optical fiber laser, and relates to the technical field of lasers. The cooling structure comprises a base, a coiling column and a bearing frame, and a first linear mounting groove is formed in the base; the coiling column is arranged on the side, close to the first linear mounting groove, of the base, a spiral mounting groove is formed in the circumferential direction of the coiling column, and the end, close to the base, of the spiral mounting groove communicates with the first linear mounting groove; and the bearing frame is arranged in the circumferential direction of the coiling column, a second linear type mounting groove is formed in the bearing frame, and the second linear type mounting groove communicates with the spiral type mounting groove. The cooling structure provided by the invention ensures effective heat dissipation of the whole section of the gain optical fiber while avoiding the problem that the melting point position of the optical fiber is broken.

Description

technical field [0001] The present application relates to the technical field of lasers, in particular to a cooling structure, a laser amplifier and a fiber laser. Background technique [0002] A fiber laser refers to a laser that uses a glass fiber doped with rare earth elements as a gain medium, where the fiber is usually coiled. However, in existing fiber lasers, the optical fiber used as the gain medium has problems such as crossing and suspension, which affect the heat dissipation of the optical fiber, so that this part of the optical fiber is burned due to overheating. Contents of the invention [0003] The application provides a cooling structure, a laser amplifier and a fiber laser to ensure effective heat dissipation of various parts of the fiber. [0004] This application provides: [0005] A cooling structure for a laser amplifier comprising: [0006] The base is provided with a first linear installation groove; [0007] The coiled column is arranged on the ...
