We report on an all-normal-dispersion mode-locked fiber laser based on a large-mode-area Yb-doped microstructure fiber and using a high nonlinear modulation depth semiconductor saturable absorber mirror. The laser delivers of average output power with positively chirped pulses at a center wavelength of . The pulse repetition rate is , which results in an energy per pulse of . These pulses are extracavity dechirped down to by using bulk gratings. The average power of the dechirped pulses is , which corresponds to a peak power of more than .
