Description

Optical fiber combiner's group restraints device

Technical Field

The utility model relates to an optical fiber technology field especially relates to a group of optic fibre beam combiner restraints device.

Background

The optical fiber beam combiner is a core component for realizing high-power optical fiber laser, and performance parameters of the optical fiber beam combiner directly influence the output power and the beam quality of the optical fiber laser. The key technology of the optical fiber combiner is overcome, the development of the high-efficiency and high-power optical fiber combiner is realized, powerful technical support is laid for obtaining high-power optical fiber laser, and the key problem to be solved in the field of the current optical fiber laser is solved urgently.

The optical fiber combiner mainly comprises a side face coupling mode and an end face coupling mode, the side face combiner is mainly manufactured by tapering a pumping optical fiber and then radially attaching and welding the tapered pumping optical fiber to the side wall of an inner cladding layer of an output double-clad optical fiber, the end face combiner can be manufactured by tapering a plurality of optical fiber groups, cutting the optical fiber groups at the position of the cone waist and welding the output optical fiber at the end face, bundle tapering of a fused optical fiber bundle is a more critical step, and the manufacturing method of the fused-tapered optical fiber bundle mainly comprises a twisting method and a sleeving method at present.

The twisting method is that after the optical fiber group bundle is input, the optical fibers are tightly attached to each other by a twisting method, and then the optical fibers are heated and tapered, so that a fused-tapered optical fiber bundle is obtained; the sleeve method is characterized in that in the process of inputting an optical fiber group bundle, a bare fiber area or an area with a part of coating layer of an input optical fiber is inserted into a glass tube with the inner diameter slightly larger than the equivalent diameter of the optical fiber bundle, then the glass tube and the optical fiber bundle in the glass tube are tapered together to obtain a fused-cone optical fiber bundle, and then the fused-cone optical fiber bundle is cut and fused with an output optical fiber.

At present, for a high-power optical fiber laser, an end face combiner manufactured by a sleeve method becomes the mainstream, and for an N × 1 type combiner or an (N + 1) × 1 type combiner, a plurality of compact and symmetrical optical fiber bundles are the basis for manufacturing the optical fiber combiner. In the ferrule method, how to arrange the input fibers tightly without torsion stress is a key step for manufacturing the optical fiber combiner, especially for the (N + 1) × 1 type combiner, it is required that N pump fibers are symmetrically arranged around the signal fiber, and the signal fiber is located at the center of the end face. Therefore, a simple and efficient beam combining method capable of improving the beam combining success rate and efficiency is very important in the production and preparation of the beam combiner.

The existing known bundling method is basically divided into two methods, one method is to penetrate the input optical fiber into the honeycomb clamp, suspend the optical fiber, and then manually combine the input optical fiber together and penetrate the input optical fiber into the sleeve; one method is that an input optical fiber is penetrated into a honeycomb clamp, and after a sleeve is penetrated, the input optical fiber and the sleeve are placed together in ultrasonic waves to oscillate by alcohol, the former method especially examines the proficiency of a fiber penetrating technician, the accuracy of beam combination is in positive correlation with the experience of the technician, the latter method relies on the alcohol oscillation, the core displacement phenomenon that a signal fiber is not positioned in the middle of an optical fiber beam can occur to a (N + 1) x 1 type beam combiner, the time cost is increased, and the other method, such as the oscillation in the alcohol after a coarse optical fiber is welded at the front end of the signal fiber, increases the beam combination success rate; the coating layer of the bundled optical fibers is fixed in advance by using a heat-shrinkable sleeve or high-folding glue to increase the bundling success rate; the practical complexity of specially designing honeycomb fixtures into a slotted arrangement, etc., increases the time cost and interferes with the cleaning of the optical fibers, and therefore, it is desirable to provide a fiber combiner bundling device to solve this problem.
