The article explains in detail that the ITF company heat-insulates the input and output optical fibers of the coupler, and fixes both ends of the coupler on the package shell. The coupling area of the coupler using this method will be suspended in the package shell to avoid contact with the inside of the package shell. Direct contact, but using this method will also cause the heat dissipation instantaneously accumulated in the coupling area to be unable to be effectively exported, and the effect on the stability of the system is not obvious
At the same time, the vibration of the output and input optical fibers fixed on the package will directly cause the molten coupling optical fiber in the coupling area to vibrate, which will bring certain danger to the system.
At the same time, the development of domestic couplers is slow due to the lack of equipment and technology, and there are very few companies and scientific research units that have mastered coupler manufacturing technology

The invention provides an optical fiber coupler device provided with cooling fluid. The optical fiber coupler device comprises a cooling liquid passage, a cooling area, an optical fiber coupling area, packaging materials and cooling liquid, wherein the cooling area is composed of the packaging materials, the optical fiber coupling area is located in the cooling area, and a cooling liquid passage is arranged in the packaging materials. The cooling liquid is input to the cooling liquid passage so as to flow into the cooling area. The cooling liquid entering the cooling area directly contacts with the optical fiber coupling area so as to play a cooling role. The optical fiber coupler device can effectively avoid optical fiber thermal injury caused by poor temperature tolerance ability of optical fiber coating layer materials in a coupling area in an optical fiber coupler.
Description
technical field [0001] The invention relates to the field of lasers, in particular to a fiber coupler device with fluid cooling. Background technique [0002] The heat dissipation technology of components in high-power fiber lasers has gradually become a key factor affecting the laser, and the heat dissipation of the fiber coupler also directly affects the power output level of the laser. How to design a fiber coupler with better thermal conductivity has become an extension of the engineering system. a key technology. At present, in the direction of coupler production and processing, the Canadian ITF company has been leading, and has published many patents on the production method and use method of fiber optic couplers, one titled "optical fiber component package for high power dissipation", patent number US7373070B2 . The article explains in detail that the ITF company heat-insulates the input and output optical fibers of the coupler, and fixes both ends of the coupler on...
