Abstract

We numerically model fiber amplifier performance near and slightly above the mode instability threshold. These results are compared with recently published experimental work. Using weakly amplitude modulated pump light we obtain qualitative agreement with the measured instability thresholds, mode switching ranges, pixel power modulations, and modal amplitude modulations.
