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...
