Abstract

The invention discloses an optical fiber coupler for transmitting carbon dioxide laser energy. The optical fiber coupler comprises a laser input tube (3), a spherical regulator (6), a planar reflector (7), a focusing lens (8), an output light barrel (9) and a heat dissipation element (10). The laser input tube (3) is of a tubular structure and is firmly connected with a laser device support (2) by fixing screws (4), the planar reflector (7) is fixed onto the freely rotatable spherical regulator (6), the spherical regulator (6) is an arc-shaped metal block, the arc-shaped metal block is regulated so as to guarantee that light rays are transmitted along an optical axis (12) in the output light barrel (9) of the coupler, are focused by the focusing lens (8) and then are coupled into an optical fiber (11), and the heat dissipation element (10) is used for dissipating heat generated in a laser transmission procedure. The optical fiber coupler has the advantages that the transmission efficiency can be improved, loss is lowered, and the optical fiber coupler is stable in structure and convenient to use, and can be regulated flexibly.

Description

technical field [0001] The invention belongs to the optical fiber coupling technology in the field of optical fiber technology, in particular to an optical fiber coupler for transmitting carbon dioxide laser energy. Background technique [0002] Carbon dioxide lasers have high power and high energy conversion efficiency, and are widely used in practical applications. Usually, the light emitted by carbon dioxide lasers is transmitted through optical fibers and then applied. However, in the process of coupling the light emitted by the carbon dioxide laser into the optical fiber in the prior art, there is usually a relatively high energy loss, and because the light emitted by the carbon dioxide laser is in the infrared band, it is not easy to adjust the coupling into the optical fiber, and there is no mature, stable, The integrated device facilitates the transmission of carbon dioxide laser energy. Contents of the invention [0003] Aiming at the problems in the prior art, t...
