Abstract

The invention is applicable to the technical field of generation and applications of high-power mid-infrared fiber lasers and mid-infrared super-continuum spectrum source, and provides fluoride fiber and quartz fiber fusing equipment, which comprises two fiber holders and a heating device, wherein the heating device is arranged at the place where the quartz fiber and the fluoride fiber are in butt joint and close to the quartz fiber side for heating the quartz fiber, and the heating temperature is higher than a melting point of the fluoride fiber and lower than the melting point of the quartz fiber; and the two fiber holders hold the quartz fiber and the fluoride fiber respectively, adjustment is carried out in X, Y and Z directions to enable fiber cores of the quartz fiber and the fluoride fiber to be aligned and the two fiber cores are contacted, and after heating, the two fiber holders are pushed in a face to face mode along the horizontal direction to enable the fiber core of the quartz fiber and the fiber core of the fluoride fiber to be fused. The fusing equipment simplifies the fusing process, the fusing cost is low, and the fusing point after fusing has the advantages of low loss, high strength, high power resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of production and application of a high-power mid-infrared fiber laser and a mid-infrared supercontinuum light source, and in particular relates to a fusion splicing device and method for a fluoride optical fiber and a quartz optical fiber. Background technique [0002] Mid-infrared fiber lasers and supercontinuum light sources have broad application prospects in laser spectroscopy, environmental monitoring, biomedicine, lidar, national defense technology, mid-infrared basic research and other fields. In recent years, they have been research hotspots and difficult issues. Fiber-based supercontinuum light sources in the near-infrared band mostly use highly nonlinear optical fibers or highly nonlinear photonic crystal fibers as nonlinear media, and their matrix materials are all quartz glass, but quartz glass loses in the mid-infrared band due to ion lattice vibrations. It is very difficult to extend the trans...
