A theoretical model is presented to calculate the angular alignment tolerances for a 980 nm pump laser diode coupled to a cylindrical lensed fiber. Numerical calculations have been performed for round-shaped cylindrical lensed fiber. Contours of relative coupling efficiencies for vertical tilt-offset, horizontal tilt-offset and axial rotation are presented and angular alignment tolerances are calculated. The effects of cylindrical lens shape and the laser-fiber distance on relative coupling efficiency are also studied.
