Abstract：The generation of dissipative soliton resonance pulses in a passively mode-locked net-normal dispersion Er-doped fiber laser is demonstrated.The dependence of pulse characteristics on pump power and the state of polarization controllers is investigated detailed.The central wavelength is 1 557 nm, with the 3 dB bandwith of 6.66 nm.By purely increasing the pump power from 220 mW to 554 mW, the pulse duration extends from 0.78 ns to 3.16 ns, while the pulse energy ranges from 3.5 nJ to 16.9 nJ.At the pump power of 409 mW, by carefully adjusting of the polarization controller's oriention, pulse duration varies from 1.6 ns to 3.2 ns.Moreover, the chirp properties of the pulses is checked.No obvious change on the pulse profile was observed after propagation in a 25 mstandard single mode communication fiber.
