We numerically investigate the output characteristic of a gain guided, index anti-guided fiber amplifier with saturated gain. The result shows that there is an output power limitation depending on the inherent leakage loss of the fiber amplifier. But we find that the amplifier with the multimode condition can operate to get a high power output with keeping a good beam shape like a Gaussian beam.
