Description

technical field [0001] The invention relates to the technical field of deep ultraviolet single-mode polarization-maintaining optical fiber processing, in particular to a deep ultraviolet single-mode polarization-maintaining optical fiber manufacturing device, and also to a deep ultraviolet single-mode polarization-maintaining optical fiber manufacturing method. Suitable for laser, frequency standard, quantum information, biology, medicine, national defense and other fields that require UV single-mode polarization-maintaining fiber. Background technique [0002] When the optical fiber is used to transmit ultraviolet laser light, ultraviolet light interacts with quartz glass, causing color center defects in the quartz glass to change its structure, thereby preventing the transmission of ultraviolet light, increasing loss, and greatly reducing the transmission of ultraviolet light ability. [0003] In order to overcome the shortcoming of variation in the transmission performan...
