Abstract

We present comparative measurements of polarization dependent gain in neodymium and ytterbium doped fiber amplifiers. It is demonstrated, that this effect is always present in neodymium doped fiber amplifiers while under appropriate operation conditions it can be suppressed in ytterbium doped fiber amplifiers.
