Paper Abstract

We report on a all-normal dispersion mode-locked fiber laser based on a large-mode-area ytterbium-doped microstructure fiber and using a high nonlinear modulation depth semiconductor saturable absorber mirror (SESAM). The laser delivers 3.3 W average output power with positively-chirped 5.5 ps pulses at a center wavelength of 1033 nm. The pulse repetition rate is 46.4 MHz, which results in an energy per pulse of 71 nJ. These pulses are extra-cavity de-chirped down to 516 fs using bulk gratings. The average power of the de-chirped pulses is 2.3 W, which corresponds to a peak power of more than 96 kW.
