A cylindrical-lensed optical fiber is used for single-mode fiber coupling for 980-nm pump lasers. This paper proposes a new machining method for the cylindrical-lensed end of an optical fiber. The method uses the bending force of the optical fiber which has homogeneous elasticity characteristics. An analysis of the cylindrical-lens machining process reveal the influence of fiber holding angles and slope angles of the polishing plane. Experiments indicate that cylindrical lenses with a curvature radius of 3 to 5 μm can be made with good precision.
