FM mode-locked operation of a single-mode Nd3+-doped fiber laser has been achieved with an integrated fiber phase modulator. The technique permits a low-loss cavity configuration, resulting in low threshold and high slope efficiency. Pulses of ∼200-psec duration are observed at a repetition rate of 417 MHz with an average output power of 15 mW.
