A cw laser-diode-pumped Yb-doped double-clad fiber laser operating in a hybrid Q -switched regime was demonstrated. The output pulses had a duration as short as 4.2 ns, a tunable wavelength range from 1080.8 to 1142.7 nm, and a linewidth of less than 0.05 nm. Maximum peak power of ~175 kW and single-pulse energy of 1.57 mJ were obtained.
