We present a detailed experimental and modeling study of fiber lasers passively mode locked using stimulated Raman scattering. We present experimental measurements of the mode locking behavior, and use the model to elucidate the nonlinear processes that create the intracavity pulses and determine the repetition rate and the order of fundamental and Raman pulses. We also present a simple method for harmonic mode locking Raman fiber lasers.
