Problems solved by technology

The ferrule can provide sufficient protection for the optical fiber during the grinding process, and the optical fiber does not need to be pulled out from the ferrule after the grinding is completed; however, the purpose of the end-face treatment of the large-diameter optical fiber mentioned in this article is to prepare for the next step of fusion splicing, beam combining, etc. At this time, if the optical fiber is fixed in the ceramic ferrule with glue, the follow-up operation will not be carried out smoothly.

Description

technical field [0001] The invention relates to a processing device and a processing method for the end face of a large-core-diameter optical fiber, in particular to a processing device and a processing method for the end-face of a large-core-diameter optical fiber used in high-power lasers. Background technique [0002] Optical fiber end-face treatment, also known as end-face preparation, is a key process in optical fiber technology, mainly including three steps: stripping, cleaning and cutting; the quality of the end face directly affects the pump light coupling efficiency and laser output power of the fiber laser. [0003] The main factors affecting the quality of end-face grinding in optical fiber end-face processing are the installation and positioning of optical fibers, end-face grinding, inspection and testing; among them, the grinding and testing part is the most critical to the development of high-quality optical fiber end-faces, and the main factors that directly af...
