The invention provides an optical fiber coupling semiconductor laser, and relates to the technical field of semiconductor lasers. The optical fiber coupling semiconductor laser comprises a tube shell,a semiconductor laser chip, an aspheric lens, a cylindrical lens and a spherical lens, a heat sink is arranged at the bottom of the inner cavity of the tube shell, and coupling optical fibers are further arranged on the side wall of the tube shell. The semiconductor laser chip is arranged on the heat sink and is far away from the coupling optical fiber; the aspheric lens is arranged between the semiconductor laser chip and the coupling optical fiber, and the aspheric lens is close to the semiconductor laser chip; the cylindrical lens is arranged between the aspheric lens and the coupling optical fiber and is close to the aspheric lens; and the ball lens is arranged between the cylindrical lens and the coupling optical fiber. According to the optical fiber coupling semiconductor laser provided by the invention, th
