Abstract

We investigate an all-fiber all-polarization-maintaining dispersion-managed ultrafast fiber laser mode-locked by nonlinear polarization evolution in polarization-maintaining fibers both numerically and experimentally. We find that the laser can operate in different regions among a wide net dispersion, including dispersion-managed solitons, dispersion-managed dissipative solitons, bound state solitons and noise-like pulses. The laser generates the dispersion-managed soliton pulses with a maximum 3 dB bandwidth of 37.84 nm, which can be further compressed to 161.37 fs. Moreover, pulses generation simulation under different net dispersion condition has been carried out. Nonlinear pulse evolution dynamics in laser cavity has been analyzed through numerical simulation as well. The results are basically consistent with the experimental ones.
