Spatially resolved spectral interferometry is used to measure the mode content of a Yb-doped photonic-crystal fiber rod amplifier with a 2300 μm 2 mode area. The technique, known as S 2 imaging, was adapted for the short fiber amplifier at full power and revealed a small amount of a copolarized LP 11 mode. Simulations illustrate the potential for weak mode suppression in this fiber and agree qualitatively with the measurements of S 2 and M 2 . Higher-order-mode content depends on the alignment of the input signal at injection and ranged from 18 dB for optimized alignment to 13 dB when the injection alignment was offset along the LP 11 axis by 30% of the 55 μm mode-field diameter.
