 Embodiment 1: as figure 1 The selected multi-core optical fiber 1 is 3 bundled optical fibers with a core diameter of 200um, in which the length of the multi-core optical fiber 1 is 15m, the bending arc length is 16-17cm, the number of bending arc lengths is 16, and the end surface of the multi-core optical fiber 1 is coated with There are 400-700nm anti-reflection coating. The multi-core fiber 1 connector is an SMA905 connector. The disturber 2 is an electric platform that shakes up and down. The vibration amplitude of the perturbator 2 is 1mm; the perturbator 2 is equipped with a 24V DC power supply. The diameter of the plastic bobbin 3 is 10cm, and the quantity is 2, and the pressing sheet 4 is 2 polytetrafluoro sheets.
 When in use, the 532nm laser, 589nm laser and 639nm laser are respectively coupled into the multi-core fiber 1, the multi-core fiber is three bundled fibers with a core diameter of 200um; the multi-core fiber 1 is wound along the winding a...
 Embodiment 2: as figure 2 Shown is a device based on a plurality of optical waveguide interference elimination, including a multi-core optical fiber, a perturbator, and a winding shaft; it is characterized in that: the winding shaft is a cylindrical winding shaft, and the side of the winding shaft is provided with grooves in the direction perpendicular to the axis. The core fiber is wrapped in the groove along the winding shaft, and the disturber is fixed on the lower part of the winding shaft; the disturber is a vibration source that drives the multi-core fiber in the groove to shake up and down regularly, which indirectly drives the multi-core fiber to shake up and down.
 Embodiment 3: as image 3 As shown, when in use, the 532nm laser, 589nm laser and 639nm laser are respectively coupled into the multi-core fiber 1, and the multi-core fiber is three bundled fibers with a core diameter of 200um; the multi-core fiber 1 is wound along the winding axis 3, Two winding shafts 3 are selected to make the multi-core optical fiber 1 produce a bent state, and the bending arc length is π times the radius of the winding shaft 3, so that the laser mode in the multi-core optical fiber 1 can be relatively evenly distributed; by being fixed on the winding shaft 3 The perturbator 2 at the lower part drives the fixed multi-core fiber 1 to vibrate up and down, so that the phases of the multiple beams change accordingly, so as to eliminate energy peaks and valleys at the output port of the multi-core fiber 1 .
