We report on an experimental observation of modulation instability in a passively mode-locked fiber soliton ring laser. We show that although in fiber soliton lasers soliton pulses are inherently stable against modulation instability, dispersive waves caused by the periodic perturbation of solitons propagating in the cavity are not. Due to modulation instability the dispersive waves can become unstable and consequently result in the generation of new spectral components in the soliton spectrum.
