Embodiment Construction
[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to an optical fiber combiner, a preparation method thereof, an optical fiber reflected light reducing method and a semiconductor laser. The optical fiber combiner comprises an input optical fiber beam and an output optical fiber, wherein the input optical fiber beam comprises multiple input optical fibers and a conical optical fiber, one end of the conical optical fiber is connected to the input optical fibers, the other end of the conical optical fiber is connected with the output optical fiber, the outer surface of the conical optical fiber is provided with a first curing adhesive layer, and the refractive index of the first curing adhesive layer is greater than the refractive index of a cladding layer of the conical optical fiber. According to the optical fiber combiner, the preparation method thereof, the optical fiber reflected light reducing method and the semiconductor laser, the outer surface of the cladding layer of the conical optical fiber is provided with the first curing adhesive layer, the reflected light spreads to the junction of the first curing adhesive layer and the conical optical fiber and generates refraction when spreading in the cladding layer of the conical optical fiber, so that reduction of the reflected light is achieved.
Description
technical field [0001] The invention relates to the field of laser welding, in particular to an optical fiber beam combiner and a preparation method thereof, a method for reducing optical fiber retroreflection, and a semiconductor laser. Background technique [0002] Laser welding is an emerging welding process. Compared with various traditional welding, it has the advantages of high welding energy density, small heat-affected range, small deformation, and exquisite weld seam. Laser welding technology has a molten pool purification effect and can purify welding materials, which is especially beneficial for welding of the same or different materials, and is suitable for welding between the same and different metal materials, plastics and other materials. The most important thing is its high degree of automation, which plays a very important role in the current industrial development. [0003] As a new type of light source, semiconductor lasers have extremely broad applicatio...
