摘      要：The numerical study on the performance of large-mode-area （LMA） fibers coiled onto a spool in high power amplifier is carried out as the bend-induced distortion of fiber modes severely affects the output characteristics of amplifier systems. The variations for high-order mode bend distortion with different orientations relative to the plane of the fiber bend are observed and shown. Concerning the practical applications, a bend-resistant LMA fiber with the mode area larger than 1000 μm^2 and excellent highorder mode suppression is designed completely by optimizing the refractive index （RI） and dopant profile. The results indicate that a hybrid profile of RI and dopant is the best choice for LMA fiber with coiling.
