We present a fundamentally mode-locked Yb-doped solid-state fiber laser with a repetition rate of 1 GHz and a pulse duration of 48 fs. By employing nonlinear-polarization-evolution (NPE) mode-locking, the laser achieves an average power of up to 286 mW and a spectrum bandwidth of 26 nm, supporting a 48 fs pulse duration. The laser can self-start and the central wavelength is tunable from 1032.4 nm to 1035.6 nm. To the best of our knowledge, this is the shortest pulse duration directly obtained by GHz fundamentally mode-locked Yb-fiber lasers.
