RESUMO
We report on an environmentally stable, Yb-doped, all-normal dispersion, mode-locked fiber laser that is capable of creating broadband pulses with ultralow repetition rates. Specifically, through careful positioning of fiber sections in an all-PM-fiber cavity mode-locked with a nonlinear amplifying loop mirror, we achieve stable pulse trains with repetition rates as low as 506 kHz. The pulses have several nanojules of energy and are compressible down to ultrashort (<500 fs) durations.
