Multi-light guide gain amplification laser equipment

Abstract

The invention relates to multi-light guide gain amplification laser equipment comprising a plurality of laser devices, a plurality of socket type photoconductive coupling devices and a socket type multi-light guide gain amplification device, wherein the laser devices are connected with the socket type multi-light guide gain amplification device by supporting plates; and the socket type photoconductive coupling devices are connected with the socket type multi-light guide gain amplification device by a single optical fiber. The multi-light guide gain amplification laser equipment has a structure that through a photoconductive coupling seat, the socket type photoconductive coupling devices are installed on the supporting plates connected with the laser devices so that once optical fibers on the socket type photoconductive coupling devices need to be replaced, just lock nuts of the coupling devices need to be loosened; and after reinstalled, the socket type photoconductive coupling devices do not need to be adjusted, thereby being convenient for operation, saving labor and time and leading the work efficiency to be high. Besides, by utilizing a positioning fastening device and lock nuts, the socket type multi-light guide gain amplification device leads multiple beam optical fibers to be in direct butt joint with the single beam optical fiber, and any other optical lens are not needed, thereby avoiding energy loss and increasing the coupling efficiency.

AI Technical Summary

Problems solved by technology

Since the optical fiber 12 is a consumable material, and the input end of the optical fiber 12 is directly screwed into the socket coupling seat 10, it often needs to be replaced, which will easily cause the bolt 9 to loosen, and also cause the seat cover 8 to come into contact with the laser. The bonding of the tube 2 falls off, thereby causing the displacement of the fixing sleeve 17, resulting in a decrease in the coupling efficiency, and even no light output in severe cases. In addition, after the optical fiber 12 is replaced, the coupling needs to be performed again, resulting in a waste of manpower and material resources. low efficiency

In addition, the recoupling mechanism uses a lens sheet to gather multiple bundles of optical fibers into a single bundle of optical fibers, and there is energy loss through the lens sheet, resulting in low coupling efficiency and high cost

Another recoupling mechanism adopts screw adjustment and positioning, which also has the problem of looseness and displacement.
