The polarization dynamics of a unidirectional erbium-doped fiber ring laser has been observed for individual round trips in the cavity. A rich variety of dynamic states, including square-wave pulses and irregular temporal patterns, was observed as operating parameters were changed. A model with coupled delay and differential equations is used to interpret the dynamics.
