Problems solved by technology

However, the thermal conductivity of copper is still limited (the thermal conductivity of copper is 386.4W m -1 k -1 ), it still takes a relatively long time to spread the heat from a hot spot with a diameter of a few microns to the entire susceptor

Abstract

The invention provides an optical fiber device and a manufacturing method and application of the optical fiber device. Inorganic heat superconducting materials are packaged in the optical fiber device and closed space in any shape of an optical component in the optical fiber device, and heat deposition of a fiber laser and key devices and modules in the fiber laser can be removed fast and effectively. The sealing space in different shapes can be used under multiple conditions, the method is simple, manufacturing is easy, and fast heat radiation can be achieved easily. Through the method, the stability of the optical fiber device can be improved, and the service life of a laser source can be prolonged.

Description

technical field [0001] The patent of the present invention relates to the field of fiber laser technology, in particular to an optical fiber device that uses an inorganic superconducting material to effectively remove heat accumulation on the fiber laser and its key components and modules, as well as its preparation method and application. technical background [0002] Since its invention, fiber laser has been continuously improved and matured, and has been successfully applied in the field of optical communication technology. Compared with other lasers, fiber lasers have the advantages of large gain medium surface area / volume ratio, excellent dual waveguide confinement mechanism, inherent fully enclosed flexible optical path, long life, small size and light weight, etc., so they are favored. [0003] Fiber lasers can be classified in many ways, among them, according to the resonant cavity structure can be divided into Fabry-Perot cavity (F-P cavity), ring cavity, and "8" ca...
