Description

technical field [0001] The invention belongs to the technical field of laser optical fiber transmission, and in particular relates to a method for adjusting the coupling of laser light and optical fiber with two optical paths. Background technique [0002] Laser fiber transmission technology is a technology that imports the laser power output by the laser into the optical fiber to transmit it in the optical fiber. The efficiency of laser transmission in the fiber is mainly determined by the numerical aperture (NA) of the fiber, the size of the fiber and the coupling state of the laser fiber. When the fiber is selected, the coupling state becomes the determining factor. [0003] The existing laser and optical fiber coupling method is adjusted through a single optical path device. The visible indicator light in the single optical path device is coaxial with the laser and passes through the laser. The visible indicator light is the auxiliary indicator light for laser adjustm...
