Abstract

In this paper cw (continuous wave) pumped self-started, widely tunable frequency-shifted feedback Yb-doped double-clad fiber laser is experimentally studied. We observed 1GHz repetition rate with an output power 56.3mW ps pulses. The laser was capable of generating as short as 5ps pulses in the range of 1078.7nm -1140.2nm (more than 60nm). The ps pulses were self-started without any other external trigger. We used 77MHz RF signal AOM and a grating which not only forms external cavity to provide feedback, but also make the laser linewidth narrower.
