摘要
We demonstrate the sub-100 fs pulse generation from a dispersion-managed mode-locked Er:ZBLAN fiber laser at2.8μm.Both numerical simulation and experiment demonstrate that stretched-pulse and dissipative soliton mode lockings coexist in the near-zero-dispersion region of a fiuoride fiber laser.With fine dispersion management,the shortest pulse of 95 fs was obtained from the stretched-pulse mode-locked Er:ZBLAN fiber laser,with an average power of280 m W and repetition rate of 52 MHz.To the best of our knowledge,this is the shortest pulse to date directly generated from a mid-infrared mode-locked fiuoride fiber laser.
