abstract = "The scheme of N×1 multi-beam combination with single gradient-index lens (GRIN) was proposed and the coupling model was simulated with ZEMAX software. One end of the GRIN was fabricated to polyhedral convex cone with N surfaces and taken as output port, and multiple beams of light converge after passing through this plane. The influences of length of GRIN lens, angle of inclined surface and distance between of fiber end and GRIN lens on coupling efficiency were analyzed. The results show that this kind of combiner has very high efficiency for multi-beam coupling, and the coupling efficiency of N×1 fiber pump combiner reaches 97.64\%. When the length of GRIN lens was between 7.36mm and 7.96mm, the coupling efficiency of the beam combiner can be maintained above 95\%. When the slope angle {\"I}† is 40.995{\"i}' <{\"I} 43.095{\"i}', the coupling efficiency of the combined beams were greater than 97\%.",
