Abstract An actively mode‐locked fiber laser (AMLFL) based on the hybrid gain of a dispersion‐shifted fiber (as the Raman gain medium) and an Erbium‐doped fiber (EDF) is introduced. The fiber Raman gain mechanism can effectively suppress the gain competition of an EDF, which usually results into the supermode noise in an actively mode‐locked EDF laser. We experimentally demonstrated a stable AMLFL with the repetition of about 5 GHz, in which the supermode noise is believed to be suppressed by employing the hybrid gain medium. © 2007 Wiley Periodicals, Inc.
