Two Bragg gratings (FBGl and FBG2) were employed as the cavity mirrors. The Average output power  single pulse energy and pulse width of the fiber laser at different pumping powers and different repetition rates was studied. The output spectrum of the fiber laser is 0.5 nm. At maximum launched pump power of 558mW  pulse energy of about 50J and duration of 140ns was obtained at the repetition of 2 kHz.
