Abstract

The invention discloses a cooling device for an optical fiber. The cooling device comprises a shell and multiple optical fiber clamping components, wherein an annular cooling fluid passageway is formed in the shell and comprises a cooling fluid inlet and a cooling fluid outlet; the multiple optical fiber clamping components are arranged in the annular cooling fluid passageway along the circumferential direction of the shell at intervals and are used for clamping the optical fibers; and the optical fiber clamping components are provided with through slots through which the cooling fluid flows. According to the cooling device for the optical fiber in the embodiment of the invention, the cooling performance of the cooling device is improved, so that the optical fiber is rapidly cooled, the phenomenon that the optical fiber is damaged or the signal transmission of the optical fiber is influenced due to extremely high temperature is avoided, the service life of the optical fiber is prolonged, and the signal transmission stability is improved.

Description

technical field [0001] The invention relates to the technical field of signal transmission equipment manufacturing, in particular to a cooling device for optical fibers. Background technique [0002] High-power and high-energy fiber lasers and fiber amplifiers have broad application prospects in industrial processing, military and medical fields. In recent years, with the application of large mode field fiber in high power laser system. The output capability of fiber lasers has been significantly improved. [0003] With the improvement of the output capability of fiber lasers, the thermal effect caused by quantum deficits in the process of fiber laser conversion is becoming more and more significant. The thermal effect of optical fiber will lead to problems such as thermal lens effect, heat-induced energy loss, and thermal damage of optical fiber. There are many traditional methods to overcome the thermal effect of optical fiber, such as forced convection cooling heat tra...
