摘　　要：We demonstrate an all-polarization-maintaining[PM]passively mode-locked Yb^(3+)-doped fiber laser[YDFL]with a fundamental repetition rate of 1.3 GHz.The optical spectra of a linearly polarized soliton exhibit different shapes by rotating the fast axis of the fiber optical pigtail of a dispersive dielectric mirror.The oscillator provides a series of laser performance,such as a threshold pump power for continuous wave laser oscillation of 3.1 mW,an optical-to-optical efficiency for modelocking of 29%,and an integrated relative intensity noise of 0.08%.To the best of our knowledge,this is the first report of>1 GHz ultrafast all-fiber YDFL with PM architecture.
