We present a passively mode-locked side-pumped Yb-doped double-clad fiber laser, emitting around 1.05 mum. Polarization additive-pulse mode-locking technique is used. Mode locking is self-starting and produces 670 fs pulses after compression with a grating pair inserted in the cavity. The energy per pulse is 24 nJ. (C) 2001 American Institute of Physics.
