Description

technical field [0001] The invention relates to an optical fiber processing device and a processing method, in particular to a femtosecond laser-based multifunctional integrated processing device and a processing method for an optical fiber. Background technique [0002] In 1966, Gao Kun, a famous physicist known as the "father of optical fiber", proposed for the first time that the transmission loss of optical fiber in glass can be reduced by reducing the impurities in silica, so as to achieve the purpose of long-distance signal transmission . [0003] In 1970, Corning Corporation of the United States successfully prepared the glass optical fiber predicted by Kao Kun. Since the creation of the world's first optical fiber sensor, it has immediately become a sensor field in many countries with its advantages of small size, high sensitivity, low cost, good stability, fast response speed, and applicable to various complex environments. research hotspot. Optical fiber devices...
