We demonstrate an all-polarization-maintaining dual-wavelength mode-locked fiber laser by bending a section of polarization maintaining fiber for intra-cavity loss tuning for the first time. This technique provides a simple way to generate dual-wavelength pulses with different repetition rate, which is potential for dual-comb spectroscopy.
