We report the generation of Q-switched mode-locked pulses from a Nd-doped fiber laser that uses a solid-state solution of BDN-I dye as the saturable absorber and is pumped by a GaAlAs laser diode. For an absorbed pump power of 110 mW, pulses of 8-nsec duration at a repetition rate of 14 MHz can be generated under an 800-nsec-wide Q-switched envelope at a repetition rate of 10 kHz, yielding an average output power of 8 mW near 1.06 µm. This corresponds to approximately 9 W of peak power in the main mode-locked pulse.
