Abstract

The embodiment of the invention provides a feedback-type energy transmission optical fiber and an optical fiber energy transmission system and device. The feedback-type energy transmission optical fiber comprises a sensing feedback optical fiber core and at least one set of energy transmission optical fiber cores, wherein the energy transmission optical fiber cores are used for transmitting optical energy, the sensing feedback optical fiber core is used for transmitting feedback information, and the feedback information is used for representing nonlinear disturbance generated by the energy transmission optical fiber cores in the process of transmitting the optical energy, thereby realizing the feedback for the nonlinear disturbance generated in the optical fiber energy transmission process, and thus laying a foundation for taking corresponding measures in allusion to the nonlinear disturbance to reduce influences imposed on the transmission efficiency of high-power laser by the non-linear effect in the energy transmission optical fiber.

Description

technical field [0001] The invention relates to the technical field of optical fiber energy transmission, in particular to a feedback type energy transmission optical fiber and an optical fiber energy transmission system and device. Background technique [0002] Optical fiber is an optical fiber with a high refractive index pure silica material as the core and a low refractive index organic or inorganic material as the cladding. It not only has a wide transmission wavelength range, but also is suitable for laser energy transmission in the ultraviolet to infrared band. , and has the advantages of large numerical aperture, high mechanical strength, good bending performance and simple coupling, which makes the application of optical fibers in high-power laser transmission systems have incomparable advantages over other materials. Equipment using optical fibers for energy transmission has been widely used in the fields of material surface heat treatment, laser welding, laser cut...
