Abstract: In this work, we investigate an approach to scale up the output pulse energy in an all polarization-maintaining 17.3 MHz Yb-doped fiber oscillator via implementation of 25 µm core-diameter large-mode-area fiber. The artificial saturable absorber is based on a Kerr-type linear self-stabilized fiber-interferometer, enabling nonlinear polarization rotation in polarization maintaining fibers. Highly stable mode-locked steady-states in the soliton-like operation regime are demonstrated with 170 mW average output power and a total output pulse energy of $~10$ $nJ$ distributed between two output ports. An experimental parameter comparison with a reference oscillator constructed with 5.5 µm core-sized standard fiber-components reveals an increase of pulse energy by a factor of 36 with simultaneously reduced intensity-noise in the high frequency range $> 100$ $kHz$.
