Abstract

The invention relates to the technical field of cladding light stripping, and specifically relates to a cladding power stripping device and a laser device. The cladding power stripping device comprises a cooling shell, an optical fiber and adhesive layers, wherein the cooling shell comprises a cooing cavity, a first passage and a second passage, the first passage and the second passage are communicated with the cooling cavity, and the interior of the cooling shell is filled with a cooling fluid; coating segments on two sides of the optical fiber are installed on the first passage and the second passage so that a bare fiber segment is placed inside the cooling cavity in a suspended mode; the coating segments are coated with the adhesive layers so that the coating segments on two sides are adhered with the first passage and the second passage in a sealing mode respectively. The coating segments of the optical fiber are adhered with the cooling shell by using the adhesive layers, on one hand, stray light returned back to an optical fiber coating layer is peeled, and the coating layer is prevented from being heated by return light; and on the other hand, the optical fiber coating layeris refrigerated effectively through the contact with the cooling shell, and the optical fiber is prevented from being overheated, so that the stripping cladding power can be improved.

Description

technical field [0001] The invention relates to the technical field of cladding light stripping, in particular to a cladding power stripping device and a laser. Background technique [0002] At present, cladding power stripping devices are mainly realized by optical glue coating or bare fiber surface microstructure treatment. The former is to smear the high refractive index polymer material on the bare fiber to refract the light in the fiber cladding to achieve the effect of cladding light stripping; the latter is to corrode or ablate or other treatments on the surface of the bare fiber way, creating an uneven surface that scatters cladding light out of the fiber. [0003] The biggest disadvantage of using the method of glue coating for light stripping is that the glue is not transparent enough and not heat-resistant enough, and the stripped waste light will be partially converted into heat, which will cause the risk of aging and burning of the light glue. The power of ten...
