We present an environmentally-stable picosecond Yb-doped fiber laser by employing an achro- matic quarter-wave-plate (AQWP) as a pulse stabilizer in the all-normal-dispersion and polarization-main- taining linear laser cavity. It is shown that the AQWP plays a critical role to control both the polarization state and spectral filtering of the proposed mode-locked laser. The demonstrated laser generates 2-ps-long pulses with pulse energies of 1 nJ at a repetition rate of 117 MHz and parabolic spectral width of 26 nm. The funda- mental RF carrier frequency exhibits Allan deviation of 3.8 × 10-8 at 1-s averaging time and phase noise of - 95 dBc/Hz at 10-Hz offset frequency.
