Abstract

We report a compact, robust, and cost-effective ultra-short pulse fiber laser incorporating a NALM-based all-PM modelocked Yb fiber laser oscillator and an Yb-doped fiber amplifier. The Yb-doped fibers are pumped with a low-power laser diode. The laser generates 12 ps pulses at a repetition rate of 20 MHz, center wavelength of 1040 nm, spectral width of 20 nm and average power of 128 mW. We believe that this type of fiber laser is an ideal seed source for further high-power femtosecond fiber laser.
